Welcome to GWP, where we make high-quality, affordable gold wash plants for sale. Our product lineup is designed to efficiently handle anywhere from 30 to 300 tons of material per hour. Each wash plant has three proportionately sized sluice boxes designed to optimize gold recovery in all conditions.
Each machine is a complete portable plant; there is no need for additional screens or sluice boxes! At the top is an extreme duty grizzly bar section that will take up to 24-inch rocks (91 cm). Classification begins when the material is placed on the grizzly bars, and high-pressure water separates the sub-1 (25.4 mm) material from the large rocks. Next, the screen deck further classifies the material, and sub-.25 (6.35 mm) material drops into the sluice boxes, remaining sub-1 material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.The sluicing system has three boxes that are independently adjustable, and with anywhere from 20 feet of sluice box on our 50-ton units to 40 feet of wider boxes on the 200-ton units, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh! Whats the key to such remarkable recovery? Science. This portable gold mining equipment was based on the performance data found in a landmark technical report on sluice boxes and riffle systems. Watch the video of our M50 wash plant.

Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au and atomic number 79. It has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits.
Gold ore processing plant is widely used in gold ore crushing and grinding process to resize and pulverize gold ores into 10mm to smaller than 1mm particles. As gold ores VHN hardness is between 60 and 105, SBM design gold ore crushing plant and grinding machine that can process gold ore. SBM gold ore processing plant includes mainly two series: crushing and grinding machines, both of which are welcomed by our customers. SBM gold ore crusher can produce gold products with the size between cm and mm. And our gold ore grinding machine can process gold ore into powder of nm grade.
State and gold content of gold in the mineral structure can be divided into the gold mineral gold deposits of gold minerals, gold-bearing minerals and gold - bearing minerals three categories. Independent minerals, means the so-called gold gold gold minerals and gold minerals in the form of output, it is the most important modes of occurrence of gold in nature, industrial development and utilization of the main object. So far, the world has found 98 gold minerals and gold-bearing minerals, common only 47 species, and direct industrial use mineral only 10 kinds of.
3) in the industrial and scientific and technological applications. Infrared reflectance close to due to the gold have unique perfect nature, it has a high resistance to corrosion stability; good electrical conductivity and thermal conductivity; the gold nuclei having a larger neutron capture cross-section; ; also widely used in the most important modern high-tech industry, and electronic technology, communications technology, aerospace technology, chemical technology, medical technology.
Most of the gold processing plant use jaw crusher as the primary crushing. CSB cone crusher is used as the intermediate crushing. The CSD cone crusher is as the fine crushing. The equipment potential to improve mineral production capacity, crushing process transformation, improve the utilization factor of the grinding machine, taken measures to implement the more crushing and less grinding to reduce the particle size of ore into the mill.
Flotation machine (also called Flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand, to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board. When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until it becomes residue.

(A) comprehensive utilization of mineral resources, inadequate laws and regulations, the comprehensive utilization of mineral resources, preferential policies are not in place. Adopting both rich and poor, low-grade ore and to carry out the comprehensive use of recycling useful components associated with the taxes charged according to the amount and quality, increase the use of cost, profit margins are low due to the recovery of this part of the resources even needed capital subsidy, , engage in comprehensive utilization but affect the economic efficiency of enterprises.
(B) loss of mineral resources, waste and destruction Most of the gold mines, especially small-scale mining is often the case where the low level of exploration under construction. Mine put into production, infrastructure, technological transformation at the same time, the majority of small businesses in the metallurgical process technology, low management level, coupled with the initial mining program ill-considered, often resulting in a large loss of resources, waste and destruction.
(D) investment in science and technology and personnel training is not enough emphasis Currently, the gold mine of comprehensive utilization of research are still weak, the depth and breadth of the comprehensive utilization of mineral resources research is not enough. On the one hand, the industrial sector dispersion of Geology and Mineral scientific research strength is not concentrated, apparatus, equipment, poorly equipped, do not form a fist. On the other hand, the comprehensive utilization of mineral resources, a serious shortage of basic research forces. Deployment of geological prospecting work, no deployment and comprehensive evaluation study on comprehensive utilization pilot study. Existing scientific research with low conversion rates.
Once extracted, the gold ore is pulverized to prepare it for refining. The gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore.
In this refining circuit, we can use electrowining cells, electrorefining cells and remelt furnace to refine gold ore. we also can use filter presses, mercury retorts and induction refining furnace to purify gole.

After gold ore mined, firstly go through crushing process. In the gold ore coarse crushing process, jaw crusher is used as gold ore primary crusher. After coarse crushing process, screen out the fine gold ore, the gild ore with diameter more than 10 mm go through secondary crushing process, in this crushing process, standard CS series cone crusher is used. In some large gold concentrator, there is fine crushing process after secondary crushing. In this fine crushing, short head CS series cone crusher is used as gold ore crushing machine.
After crushing process, the crushed gold ore enter into ball mill evenly through vibrating screen. Ball mill is essential gold ore beneficiation machine used to grind gold ore into powder less than 200 mesh. Gold ore powder go through classification and flotation to make pure gold.
Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate. When the mined gravel is fed into the washplant. It is classified by particle size using various stationary or vibrating screens. Classifying gravels provides for more efficient gold recovery, reduced water consumption, and facilitation of mine site rehabilitation, and is practiced by most operators. The oversize material, usually larger than two inches, slides out of the washplant into a pile where it can be moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluicebox where the gold and heavy black sands are concentrated. Tailings are gravel, sand, and other materials accumulated at the end of the sluicebox. Tailings are routinely moved away from the sluicebox by a loader or bulldozer.
The water that carries the gold-bearing gravel through the sluicebox becomes sediment-laden and turbid. This muddy process water flows from the end of the sluicebox over a pile of fresh tailings into a series of settling ponds. These ponds are designed to hold the muddy water long enough for the fine sediments to settle. The physical design of the ponds depends upon the amount of water flowing through the system, the sediment characteristics of the gravels being worked, and the physical characteristics of the site. Most mines use a series of small settling ponds to permit more flexible water management. Small ponds are usually easier to build, repair, dean, replace, bypass, and rehabilitate than larger ponds. The use of pre-settling ponds is encouraged. A pre-settling pond is located in the tail race between the sluice and the first settling pond. Sands and other heavy settleable solids are collected here where they are easy to wash.
However, some zero-discharge systems do have occasional discharges, usually due to water seepage through pond dikes. This seepage almost always meets the settleable solids effluent standards, and in most cases, Is probably of better quality than the water discharged from typically operated settling ponds. I.e., less settleable solids and lower turbidity. Carefully designed and Implemented water management practices are required to achieve zero discharge of muddy water into adjacent streams. Water used in the sluicing process Is pumped from the nearby stream through the washplant and into the settling ponds. Water Intake from the stream Is suspended when the ponds contain adequate water to support continued sluicing operations by recycling pond water to the washplant. In some cases, groundwater seepage Into the settling ponds may be sufficient to eliminate the need for adding stream water to the system. The practice of zero discharge and the recycling of mine water contributes to compliance with federal effluent limitations and State water quality standards.
Placer mining involves equipment ranging from a simple gold pan all the way up to trucks, excavators, and a gold wash plant.This type of gold prospecting usually involves less investment and will consistently yield small amounts of gold, with occasional bonanzas for those who are persistent. If you can learn to reliably return from every trip with decent concentrates, so that over time you fill a five-gallon bucket, and then maybe even a fifty-five-gallon drum, with black sands, magnetite, ilmenite, rare earth elements (REEs), and gold, you will be rewarded in the long run.
Either way, your long-term goals are your own.Very few prospectors are simply in it for the money, looking at this as a way to become a millionaire overnight. Some of us just like to get out of town, camp in the mountains, and enjoy the spirit of the outdoors. Some people like to work up a little sweat and appetite, improve their health, and learn a little. Some of us like to solve problems and run machinery, and enjoy the challenge of keeping a pump going or making sure the sluice is running right. Still others like the wildlife, the scenery, and the historical importance of the Wild West, and bring back their riches as photos and videos. In each case, if you toss in a little gold fever as motivation and stay scientific about your sampling and exploration, you will prosper far and above the value of your recovered material.
Still, a nice payday is always a treat. One sure way to reach that goal is to keep trying. Keep practicing, keep exploring, and keep getting out in the field. Another truism that seems to hold is that the farther away from civilization you get. the better your chances.
The development of a load/placer mine and the selection of the proper gravity recovery plant is more difficult than most people realize. Television shows have glamorized mining making it look like anybody can start a mine with little to no experience. What people dont realize is that mining is a structured engineering discipline taught at university. Just as you should not build your own bridge without knowledge of civil engineering, you should not think becoming a miner is a simple task. If you have no experience in the mining field you need to get educated about the process before you embark on this adventure. We have compiled a basic guide to assist in that process.
The terminology used for this type of mining is often interchanged. The term for the type of deposit under consideration is alluvial. Alluvial deposits are formed when the gold has migrated from its original deposition by weathering to a new location often inactive stream beds or in historic watercourses now overlain by sediments or glacial sediments.
In general Placer Mining is typically the recovery of gold from stream sediments through the use of dredges and sluices or other gravity means. Load mining generally involves the stripping of an overburden layer (soil) to uncover the underlying gravels that contain the gold. These deposits are often mined with mobile equipment and the ore trucked to a gravity treatment plant.
1. Permitting am I allowed to disturb the land excavating pits, leaving tailings behind, water usage, noise, air quality. In most cases you are not allowed to simply start mining even on your own land without the proper permits.
2. Resource estimation how much gold is present (grade and tonnage) and what does the deposit look like over burden depth, ore depth, gravel size. Generally, a placer resource is established by drilling or augering holes around the deposit to delineate the extent of the gold. This is often combined with field gravity recovery testing to provide an estimate of the recoverable grade.
6. Mine plan do you have a mine plan where are you going to mine first, where is the overburden going to be placed, where are the tailings going to be placed, is the plant going to be in one spot or moved during the mine life, what are the haulage distances. Is this a seasonal operation?
Mine Conditions Where is your project located? terrain, climate, infrastructure variables How large is your concession? Is a mobile or fixed plant right for this application? How many yards/hour (m/hr or tons per hour) do you want to process? How much water do you have available (GPM or m/hr)? Is there power available from the grid or do you required generation?
Plant Characteristics Are you looking for a mobile machine that you move regularly or a stationary plant that you haul your ore to? What type/size of equipment will you be feeding the plant with (front end loader, dredge pump, other)?
Feed Characteristics Ore consistency: What is the estimated maximum boulder size (in, mm)? Is there significant clay present? What is your maximum gold size (mm or um)? Is there fine gold present, what is the typical size (um)?
8. Economic Model Once you have made some initial assumptions you need to develop an economic model (even a basic one) so that you know if the project is viable before you start. No matter what type of project you should try and establish some basic economics unless this is just going to be a small hobby operation where profit does not matter. There are a lot of assumptions required to develop the model and you need to be realistic in your assessment. Add contingencies for operating costs of 10-15% and 20-30% for capital costs.

After the first stage crushing process, the ore material enters the double-layer vibrating screen, the crushed upper layer material with middle layer material enters the second crushing stage, the outlet material from the first crushing stage and the second crushing stage into the screening procedure. The screened material is ground by the first stage ball mill, a closed circuit grinding system is composed of the ball mill and the classifier. The staged overflow is classified by the cyclone and then enters the second-stage ball mill for re-grinding, and then forms a closed-circuit grinding with the cyclone. The gold-plating equipment cyclone overflow firstly performs preferential flotation, and the foam products are subjected to secondary selection and a three-time selection to become concentrate products. After the preferential flotation, the tailings undergo a rough selection, a selection, and two The selection process of three selections, three selections, and one sweeping, one selected tailings and one sweeping foam product enter the cyclone for re-classification, re-selection, secondary selection and one fine The selection constitutes a closed-circuit selection, and the three selections and the second selection constitute a closed-circuit selection.
Gravity beneficiation is an ore dressing method which according to mineral density and plays an important role in contemporary mineral processing methods. The gravity separation equipment includes spiral chutes, shaker tables, jigs and short cone cyclones.
1. Mercury amalgamation-gravity separation This process involves gravity separation and then mercury amalgamation or mercury amalgamation before gravity separation. The former method is mostly used for the placer gold which with low gold content, or the surface contaminated ore. The latter is mostly used for the quartz vein gold-bearing sulfide ore. 2. Gravity separation (amalgamation)-cyanide process This gold processing method is suited for the quartz vein type gold-bearing oxidized ore which with uneven disseminated grain size and high oxidation degree, the gold-bearing ore basically free of copper, arsenic, antimony, etc. 3. Flotation process This processing method is suitable for the quartz vein gold-bearing ore, gold-bearing altered rock type ore and sulfides ore which with fine gold particle and good floatability, widely applied in the medium-large good mining plant. 4. Gravity separation (amalgamation)-flotation process This procedure is applicable to the uneven disseminated grain size and low sulfur quartz veins containing gold ore. Since the monomer-dissociated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This process is a widely used process in China's gold plant, in which the recovery rate of gold can reach 30-60%. 5. Cyanidation (full mud cyanidation) process Applicable to gold with a higher emerald grain size, a deeper iron ore-bearing pyrite quartz vein type ore, or a gold-altered diorite-type ore. The ore is required to contain no elements harmful to cyanidation such as copper, arsenic or antimony. 6. Flotation-Cyanide Process This process is suitable for the treatment of gold-bearing iron ore quartz vein ore with gold and sulfide symbiosis. It is also suitable for gold-bearing granite fracture zone altered rock type ore, especially for high sulfur ore. To apply. This process is also one of the common processes in China's gold mines. 7. Flotation-baking-cyanide combined process This procedure is applicable to gold-bearing quartz vein type ores containing elements such as arsenic and antimony. The roasting process is a preparation for cyanidation in order to remove elements that are harmful to cyanidation.
