gold leaching agitation tanks

gold leaching agitation tanks

The mixing of solids suspended in a fluid medium is still largely an art. The development of fundamental laws governing the operation is complicated by the large number of variables involved, some of which can hardly be evaluated in mathematical terms.

Practical studies of the circulation patterns of the more common types of agitators are to be found in chemical engineering literature. In one of the more recent articles on this subject the author summarises a few rules for agitator design as follows:

For ratio of tank diameter divided by impeller diameter, take 4:1 for simple blending of light material; 3:1 for the average job, and 2:1 for heavier density or high viscosity material. The approximate impeller speed should be 700 peripheral feet per minute for turbine-type impellers and 1000 to 1500 ft. per min. for the propeller type. The horsepower requirements can be estimated from data given in the various engineering handbooks.

Because in certain cases power input appears to be directly related to agitator performance, i.e., in gas absorption and emulsification, a rather intensive study has been made of the problem. Thomas Hooker investigated the power function M versus agitator Reynolds number Re. Secondary dimensions such as pitch, liquid depth, and blade width were expressed on a dimensionless basis by dividing by the primary dimension of the agitator span L. The standard systems chosen for this work were those involving axial flow, tangential flow, and radial flow, and plots showing the above relationship for each system are given, in addition, to a number of the design-factor plots. It is suggested that the agitator power consumption can be predicted for most installations to within 20 per cent using this method.

An earlier paper reports the results of experimental work on the effect of the number, size, and position of baffles on agitator power consumption. The so-called fully baffled condition, when the input reaches a maximum, is discussed.

Violent agitation has no recognised value in itself, but ample oxygen supply is essential to promote the reaction between gold, silver, and cyanide. Control of aeration during agitation is essential, since excessive aeration usually results in greater consumption of lime and sometimes of cyanide, with no increase in extraction.

Length of contact and dilution during agitation vary considerably for different ores. For gold ores agitation periods vary from 16 to 48 hr., probably averaging 30 hr., and for silver ores nearly twice this period. Dilution during agitation varies from 1 of solution to 1 of solids by weight to 3 of solution to 1 of solids, occasionally higher, probably averaging 2 to 1. Operation is continuous through a series of agitators, preferably three or more, to minimize any tendency for short-circuiting. Change of solution during agitation by means of a thickener placed between agitators often improves extraction, particularly when silver or other ores requiring long periods of agitation are being treated.

The first agitators used in the industry were of thesimple rotating-paddle type. These, however, required a large amount of power and did not give uniform suspension or satisfactory means for controlling aeration in cyanidation leaching.

Devereux. The Devereux is a propeller-type agitator in which a propeller revolving centrally in a round, flat-bottomed tank at about one-third the depth of the tank above the bottom forces the pulp downward to the bottom where it is deflected along the bottom and up the tank sides, creating a vortex at the center in which air is drawn into the pulp. This machine, while simple mechanically, requires relatively high power. At one plant an 18- by 18-ft. Devereux requires 15 hp. when agitating a pulp containing 62 per cent solids.

Turbo and Wallace. The Turbo and the Wallace are high-speed impeller types of agitator imparting high velocity to the pulp and are suited for relatively small-diameter flat-bottomed tanks. The Turbo may be provided with an impeller near the pulp surface whereby large amounts of free air may be drawn into the pulp and emulsified.

The Wallace consists essentially of an impeller or rotor near the tank bottom and at the lower end of a stationary vertical pipe which extends nearly to the pulp surface. The action of the impeller creates a circulation of pulp down the pipe and into the impeller. When the pipe is properly placed, free air is drawn into the top of the pipe together with pulp and disseminated throughout the tank. The pipe may have auxiliary openings to draw in pulp from different levels in the tank.

The Brown or Pachuca agitator, as it is most commonly known, originated in New Zealand in the early days of cyanidation leaching, the invention of F. C. Brown. It later became popular in Mexico, and to a limited extent its use has spread to other countries.

The Pachuca agitator is an all-air agitator which consists of a central stationary air-lift pipe in a circular cone-bottomed tank of varying dimensions, usually from 5 to 18 ft. in diameter and 20 to 60 ft. in depth.

Relatively large quantities of high-pressure air are required, and with some ores considerable difficulty results from the building up and sloughing off of solid masses from the tank sides. The height of the Pachuca is a further disadvantage and usually necessitates pumping of the pulp.

The Pachuca agitator is still to a large extent retained on the Rand, about one-half of the continuous-treatment slime plants using it in their flow sheets. A recent paper states where maximum aeration of pulp is essential for optimum extraction, it appears that the Brown tank (Pachuca) is superior (to the Dorr) in maintaining the oxygen content of the pulp at a higher level. This statement is based on some recent work at the the Geduld Propietory mines and the Sub Nigel, Ltd., but tests made in the early 1920s indicated that, if additional aeration is supplied to the submerged rake arms, the Dorr agitator can be made as effective an aerator as the Pachuca and at a lower operating cost owing to lower total air requirements and the fact that it is not necessary to elevate the pulp.

The pulp and coarse solids from the bottom of the tank are elevated by means of air through the revolving hollow central shaft to a head casting above the pulp level and thence distributed through two revolving launders over the surface of the pulp. Coarse solids settling on the bottom of the tank are raked to the central lift by two plow arms attached to the shaft. The rate of circulation in the tank is controlled by means of the air supply to the central lift.

This agitator was developed at Noranda mines to handle the heavy sulphide concentrates which required also a high degreeof aeration for optimum extraction and economy in reagents. In this machine the settled sands raked to the center of the relatively deep tank are returned to the top of the agitator by an outside air lift while additional aeration is supplied by a series of jets placed around the tank and connected to a circular header above. Tank areas and total air supply are given in Table 13.

A common problem in mill design is to determine from the experimental data obtained by batch tests the number and capacity of agitators that must be used in a continuous system in order to approximate the same degree of dissolution. A mathematical analysis of this problem is described by McMullin and Weber in Trans. 31, A.I.Ch.E409, 1935.

As a result of further studies along these lines, Dr. E. J. Roberts has prepared the graph shown in Fig. 30, which expresses the relationship between the ratio of volumes for continuous and batch systems and the percentage of in-completion of the reaction for series of one to four agitators.

Commenting on this relationship, Dr. Roberts points out that the numerical values obtained should be taken for general guidance only because the assumptions involved in the calculations are first approximations only based on the hypothesis that the rate of dissolution is a function of the continuously diminishing surface of the substance being dissolved. In the case of the extraction of gold by cyanide solution, it is probable that other factors such as the rate of diffusion through pores in the rock particles, intensity of agitation, etc., affect the over-all rate ofdissolution. For precise design, therefore, it is recommended that the MacMullin method be followed, which involves running tests to determine the type of reaction empirically.

As an example of how Fig. 30 may be used, take the case of gold being dissolved by cyanide solution. Assume 98 per cent completion of reaction is desired, or 2 per cent in-completion. Referring to the graph, the required reaction could be completed in one agitator if the volume relationship was 6 to 1. In other words, if 10 hr. was required by batch agitation to extract 98 per cent of the gold which could be extracted in infinite time, a single continuous agitator would have to be large enoughto give 60-hr. detention time. However, if two agitators were used in series, the combined volumes would have to be large enough to give only 21.6-hr. detention, while in the case of three agitators in series the time is reduced to 16.4 hr., or 5.5 hr. for each agitator.

In actual practice, an economic balance covering first cost and operating costs for the various combinations of agitators indicated would have to be worked out and the most favorable of these selected.

Silo tanks for milk reception belong to the storage category and have been described in Chapter 5, Collection and reception of milk. They vary in size from 25 000 to about 150 000 litres and the wetted surfaces are made of stainless steel. They are often placed outdoors to save on building costs. In these cases, the tanks are insulated. They have a double shell with a minimum of 70 mm mineral wool insulation in between. The outer shell can be of stainless steel, but for economic reasons, it is usually made of mild steel and coated with anti-corrosion paint. To make complete drainage easy, the bottom of the tank slopes downwards with an inclination of about 6 % towards the outlet. This is a statutory requirement in some countries. Silo tanks are fitted with various types of agitators and monitoring and control equipment. The number and size of the silo tanks are determined by such factors as the milk intake per day, the number of days per working week, the number of hours per working day (one, two or three shifts), the number of different products to be manufactured, and the quantities involved.

These tanks are used to store a product for a short time before it continues along the line. They are used for buffer storage, to level out variations in flow. After heat treatment and cooling, the milk is pumped to a buffer tank, and from there to filling. If filling is interrupted, the processed milk is buffered in the tank, until operation can be resumed. Similarly, milk from this tank can be used during a temporary processing stoppage. In storage tanks, (Figure 6.9.3), with a capacity of 1 000 to 50 000 litres the inner shell is made of stainless steel. The tank is insulated to maintain a constant product temperature. In this case, the outer shell is also of stainless steel, and there is a layer of mineral wool between the shells. The storage tank has an agitator and can be fitted with various components and systems for cleaning and for control of level and temperature. This equipment is basically the same as previously described for silo tanks. A good general assumption is that the process requires a buffer capacity corresponding to a maximum of 1.5 hours normal operation, i.e. 1.5 x 20 000 = 30 000 litres.

As the name implies, these tanks, (Figure 6.9.4), are used for mixing different products and for the admixture of ingredients to the product. The tanks may be of the insulated type or have a single stainless steel shell. Equipment for temperature control may also be fitted. Insulated tanks, with mineral wool between the inner and outer shells, have a jacket outside the inner shell through which a heating/cooling medium is pumped. The jacket consists of welded-on channels. Agitators for mixing tanks are designed to suit the specific application.

In these tanks, Figure 6.9.5, the product is treated for the purpose of changing its properties. They are widely used in dairies, e.g. ripening tanks for butter cream and for cultured products such as yoghurt, crystallization tanks for whipping cream, and tanks for preparing starter cultures. There are many different types of process tanks. The application determines the design. Common features are some form of agitator and temperature control. They have stainless steel shells, with or without insulation. Monitoring and control equipment may also be fitted.

These problems, as well as some others dealt with here, are often resolved by fitting a balance tank in the line on the suction side of the pump. The balance tank keeps the product at a constant level above the pump inlet. In other words, the head on the suction side is kept constant. The tank in Figure 6.9.6 contains a float connected by a lever to an eccentrically-pivoted roller that operates the inlet valve on the tank. As the float moves downwards or upwards with the liquid level, the valve is opened and closed respectively. If the pump draws more from the tank than flows in at the inlet, the level drops and the float with it. The valve opens and lets in more liquid. In this way, the liquid in the tank is kept at a constant level. Today the same functionality is usually achieved with level sensors that control a regulating valve. The inlet is located at the bottom of the tank so that the liquid enters below the surface. Consequently, there is no splashing and, above all, no aeration. Any air already present in the product on entry will rise in the tank. Some deaeration takes place. This has a favourable effect on the operation of the pump, and the product is treated more gently. The balance tank is often included in a recirculating system where liquid is returned for recycling, e.g. as a result of insufficient heat treatment. In this case, a temperature indicator actuates a flow diversion valve, which directs the product back to the balance tank. This causes a quick increase in the liquid level and an equally quick movement of the float mechanism to close the inlet valve. The product then circulates until the fault has been repaired or the plant is shut down for adjustment. A similar procedure is employed for circulating cleaning solution when the line is cleaned.

It is a mechanical piece of equipment used to fulfil a specific mixing or process task. These tasks could be anything from suspension of solids, to combining liquids or liquid-solids, for example. A basic mixer, in our instance, is made up of a motor, gearbox (unless a direct drive is used), coupling, shaft, hub(s) and blades. This is illustrated in the drawing on the right:

Propellers and impellers both provide thrust however, they do it in different ways. A propeller is a fan which propels a fluid by pushing against it. Basically, it converts rotational motion into linear motion. An impeller, on the other hand, is a rotor that produces a sucking force and makes up part of a pump.

The higher your Reynolds number, the more turbulent the flow will be; and the smaller the number, the more laminar. For mixing, turbulent flow is the easiest form of a fluid regime to mix your product. The higher the viscosity, the lower your Reynolds number will be inevitably leading to a more laminar flow. When we design an agitator for these conditions, we need to consider that the product will not mix as easily as lower viscosity fluids or fluids in the turbulent regime. In many instances, designs done in the laminar regime would require a different impeller, a larger impeller diameter or increased power to achieve the desired result.

An agitator is a purpose-built piece of machinery designed specifically for the in-tank conditions. If these circumstances were to change, it is possible that your mixer performance will be affected. Examples of these changes are:

AFX can also provide an onsite maintenance service with agreed intervals to suit your schedule and budget. Our service personnel will look after your agitators wellbeing and increase its operational life.

GEARBOXES On our larger agitators, gearboxes are designed to incorporate a dry well and heavy-duty output bearings. In the majority of instances, we also allow for an extended bearing distance. Normally, gearboxes are selected on torque alone, but with agitators, the overhung load is large, and the drive is subjected to high external loads. Our selection, therefore, doesn't only cater for the transmission of power, but also its ability to withstand external forces.

BASES With tanks being larger, the structures the agitator needs to mount onto becomes more susceptible to inaccuracies and misalignment. With the intention of saving costs, many manufacturers allow their gearboxes to be bolted directly onto faulty beam structures. By mounting a machined gearbox directly onto a fabricated structure, it preloads the housing. This causes additional stress within the housing itself. During operation, this misalignment, combined with any twisting of the beams, will cause premature casing failure. AFX-designed gearbox bases have machine mounting surfaces that don't need shimming and won't preload the gearbox casing. Bases are designed to withstand much greater loads than what the agitator is subjected to. This enables the base to increase the rigidity of the structure.

Our extensive range of peristaltic hose pumps includes one of the largest pumps of this type in the world. Our 150mm pump has a maximum flow rate of 147m/hr and can deliver pressures up to 10 Bar. These units are ideal for thickener underflow applications.

AFX PUMP SERIES The AFX Peristaltic pump range has been designed to be a robust pumping solution for high viscosity, high solids (abrasive), high density slurries and liquids for a wide array of applications and industries including mining, chemical, food and beverage, pulp and paper, petrochemical, pharmaceutical, agricultural, water treatment and many more. Building on a proven concept our latest development is the AFX PUMP SERIES which was specially adapted to further improve the products high performance, durability and low maintenance.

All AFXs products are designed to deliver exceptional performance, but what sets this pump apart from its competitors is its cost-effectiveness and reliable operation. AFX can demonstrate measurable savings when using the AFX PUMP over that of its competitors, including energy savings and maintenance downtime savings of up to 50% compared to traditional peristaltic hose pumps. The pumps are self-priming, fully reversible, highly durable, easy to maintain, can be run dry for extended periods without damage, and offer flow rates from 40 l/hr to 150 000 l/hr.

OPERATING PRINCIPLE The internal workings of each pump comprise of a rotor block with solid rotating rollers. The pumping action results from alternately compressing and relaxing a specially designed high-pressure peristaltic hose between the pump housing and the pump compression rollers to create an airtight pocket. The fluid is pushed along the hose towards the discharge by the compression rollers, creating a positive displacement. The reopening hose behind the roller draws more fluid into the pump through the suction. Due to this method of operation where there is 100% hose closure at all time, the pump is on its own a non-return mechanism. This ensures excellent metering accuracy and reduces the need for additional equipment downstream.

APPLICATIONS The AFX PUMP SERIES are commonly used in applications where the product to be pumped has a high solids content and/ or viscosity, such as thickener underflow, slurry transfer and chemical transfer or dosing applications; but are popular solutions for many other applications which include:

PUMP SELECTION Boasting eleven AFX peristaltic pump models with flow rates between 40 l/hr to 150 000 l/hr across the range the AFX PUMP SERIES have become industry favourites across many countries. We attach the same care and dedication not only to pump and hose design but also to the selection and application of our pumps. To ensure optimum performance and product life, as well as to minimise operational cost and maintenance downtime, every AFX pump is carefully selected, configured and equipped for a specific applications requirements by an experienced application specialist.

To eliminate potential design errors, AFX ensures that all its manufacturing drawings are produced in 3D. A process referred to as Finite Element Analysis (FEA) is used in instances where large, or infrequent components are designed. The analysis combines all the operating loads of the system, allowing the designer to see potential flaws before manufacturing takes place.

MOUNTING BASE Mounting bases must accommodate machined gearbox bases and fabricated beam structures and prevent twisting and stressing of gearbox casings a common cause of failure of proprietary drivers.

AFX makes use of Finite Element Analysis (FEA) for its designs allowing its engineers to model the combination of loads applied to the actual components resulting from the impellers rotation system and its interaction with fluids and slurries. By making use of this method, the applied bending moment, torque and thrust can be predicted and adequately accommodated in the design. Detailed FEA is required in instances where important components carry critical loading. Shown below are some examples of our FEA applications.

Computational Fluid Dynamics (CFD) is the method of applied mathematics, physics and computational software used to visualise how a gas or liquid flows, as well as how a gas or liquid affects certain objects as it flows past. AFX makes use of CFD in numerous applications to calibrate flow numbers, view velocity vectors and assist with solving process problems.

Our range of portable top entry mixers suited to smaller mixing and blending applications provides the customer with the freedom to decide how to mount, move or permanently fix the agitator. Portable air or direct drive units are supplied with swivel brackets perfect for mounting at the desired angle. Some small direct and gear drive units can be wall mounted for applications with multiple containers. Angular mounted or angular offset agitators are commonly employed for use in cylindrical mixing vessels which are un-baffled. The portability of our small agitators gives good flexibility, allowing freedom to move from one vessel to another. Our applications engineers are on hand to advise the most suitable configuration for your needs, to ensure these versatile agitators offer the user the most economic mixing solution.

As the name suggests, these agitators are directly powered by the installed motor. Being a very cost-effective and quick agitator to supply, there are many small and easy blending applications where direct drive agitators are well suited. Using our range of F3 axial flow impellers, the agitator delivers on the process requirements. Most commonly used in small pilot and bench plants, pharmaceutical laboratories, test laboratories in research and development departments as well as in batch development within the personal care industry, these direct drives are adaptable, easy to use, require little maintenance and ensure that the desired process outcomes are met. Available with variable speed drives and various mountings, we are certain that we will meet your process solution.

As all mixing and blending applications differ, the demands placed on the agitator do too. In some applications, the use of a direct drive is just not possible for various mechanical reasons. Keeping this in mind, we offer small portable gear driven agitators. Sizing the agitator to suit your vessel as well as to ensure that the desired process is achieved, we strive to bring you the best top entry solutions. Tailoring our manufacturing methods, we can keep costs competitive and guarantee the best quality agitator. The majority of these units can be found in applications where a solid suspension is required, or the viscosity of the product is high within the vessels or where the mixing application is arduous. These agitators power a large segment of the market, where the demand has not waivered. Available with a selection of various options to ensure that the agitator is customised to suit your specific needs and process requirements, our range of AMX portables are a solution within the various markets, and they continue to expand their application reach.

AFX offers small electric or pneumatic agitators perfectly suited to small instant blending applications in 210-litre drums, where flash mixing and blending is required. Although designed primarily for 210-litre drums, these adaptable mixers can be easily adjusted to suit smaller containers by changing the shaft length. Two standard designs are available to suit both open and closed top drums. For closed top drums, agitators are supplied with a dual bladed folding impeller designed to fit through the bung hole on the top of the closed drum. The agitator comes complete with a threaded bung hole adaptor for mounting and operating purposes. For open top drums, agitators are usually supplied with our fixed three bladed F3 impellers. These units are cost-effective, efficient, easy to operate and maintain. Their portable design allows the freedom to move from one vessel to another. Operating between 300 3000 rpm. The wetted parts are manufactured from stainless steel and the aluminium housing aids the light-weight design of this agitator. These agitators are the number one solution for light drum mixing and blending applications.

AFX offers a range of Intermediate Bulk Container (IBC) mixers (also known as TOTE or flow bin mixers) specifically designed to handle mixing duties within the container. Our mixers handle varying ranges of viscosity, densities and other processing requirements. The main feature of AFXs design is found in a range of folding impellers. These impellers are based on our range of high-efficiency hydrofoils that can fold in to facilitate fitting through the limited container opening, without the need for any modification to the container. The container openings vary from 100mm (4) up to 200mm (8). Our stainless steel impellers are available in varying diameters from 132mm (5,2) up to 435mm (17,1) which allows us to meet most application requirements. With the impeller being a hydrofoil the design offers the efficiencies of a fixed bladed impeller system. Our design results in lower power consumption compared to our competitors while maintaining the same results. This improves the process efficiencies and reduces the mechanical loading on the agitator. This reduced mechanical loading allows the agitator to be lightweight and durable.

The need for larger mixers has increased in recent years, mainly due to the industrys requirement to expand operations, or to keep production costs as low as possible. At AFX, we customise our top entry mixers to accommodate your process. Our top entry mixers are available in different technical specifications and can be used for specific purposes across different industries. In the past, large top entry units were more commonplace in the mining industry. However, this trend is now changing with other industries now also requesting larger and more specialised mixers.

As agitators become larger, the loading requirements increase considerably, and every component is looked at individually, ensuring it is robust enough to handle the application. At AFX, all design work is further scrutinised using Finite Element Analysis (FEA) to ensure that failures do not occur. Many companies tend only to use FEAs once they have experienced problems or failures. We use FEAs and our design know-how to avoid problems before they happen.

Components are isolated and designed to handle loads far more than what they would experience during operation. Our software allows us to predict and simulate very accurately what loads will be experienced during operation. Even with this in mind, all our designs are conservative and can tolerate any fluctuating loads and peaks that the plant may experience. These components also have unique design features, such as:

On our larger agitators, gearboxes are designed to incorporate a dry well and heavy-duty output bearings. In the majority of instances, we also allow for an extended bearing distance. Normally, gearboxes are selected on torque alone, but with agitators, the overhung load is large, and the drive is subjected to high external loads. Our selection, therefore, doesnt only cater for the transmission of power, but also its ability to withstand external forces.

With tanks being larger, the structures the agitator needs to mount onto becomes more susceptible to inaccuracies and misalignment. With the intention of saving costs, many manufacturers allow their gearboxes to be bolted directly onto faulty beam structures. By mounting a machined gearbox directly onto a fabricated structure, it preloads the housing. This causes additional stress within the housing itself. During operation, this misalignment, combined with any twisting of the beams, will cause premature casing failure. AFX-designed gearbox bases have machine mounting surfaces that dont need shimming and wont preload the gearbox casing. Bases are designed to withstand much greater loads than what the agitator is subjected to. This enables the base to increase the rigidity of the structure.
