iCON is a family of Mineral Processing Products specifically designed to recover fine gold. iCON was designed by the professional Engineers at Falcon Concentrators and uses the same patented technologies used at the largest mines in the world.

iCON uses the same proven technology as the Falcon brand of professional mining products: it was designed by Falcons engineers and is now a product of iCON Gold Recovery Corp. Our History and Environmental Responsibility are discussed on our website.

Throughout history gold processing has been plagued with inefficiency and contamination. Millions of dollars of fine gold have been discarded in the tails or washed down the creek due to inadequate processing.

Processing large material that is known to have no value costs both money and time. With classification, time, energy and money will not be wasted processing excess material that is known to have no value.

For example, if you know that your largest gold is .5mm then there is no reason to put 10mm material through your process. Also, the large feed will affect the efficiency on any process. The large material will hinder the recovery of the finer materials.

Your feed will be screened to 2mm (or less based on your results) before processing in the concentrator. Any material larger than the screen will pass over the nugget trap. This will give the user confidence that they are collecting the BIG gold while minimizing the feed to the concentrator and maximizing its efficiency.

discussion on the configuration forms of knelson concentrators in gravity separation process

In recent years, due to the rapid rise of gold price, the economic benefits of gold mining and production companieshave been significantly improved, and a large number of advanced world-renownedmineral processing equipment have been applied in China,due to their advantages of high equipment efficiency, low failure rate and easy operation, as well as simple process configurationand so on, they are generally recognized by mine and industry experts, these equipment include: crushing and screening equipment produced by Metro and Sandvik, Knelson Concentrator, etc. They have brought revolutionary development to China's mineral processing production, and the scale and technical indicators of mineral processing have also been greatly improved.

ShanDongYinGeZhuang Gold Mine was the first to importthe KnelsonConcentrator into China for recovery the coarse gold.Later, HeNan JinQu Gold Mine and Shanxi YiXingZhai Gold Mine alsosuccessively applied it in coarse goldrecovery. Since then, the Knelson Concentratorhas been rapidly promoted and applied in other mines in China, and configuration forms of Knelson Concentrators in gravity separation process has also been developed.

The Knelson Concentratorcan be configured before classification or after classification. Because the spiral classifier is often used in the classification of gold mineral processing plantsin China, the former configurationis more used in China.However, hydrocyclones are often used for classification abroad, therefore, Knelson Concentrator is usually used to separate coarse gold from underflow by hydrocyclones. Knelson Concentrator uses a large amount of water, resulting in a large water content of tailing after separation, so it must be concentratedbefore returning to the ball mill for regrinding.

Since the feed size of Knelson Concentrator must be less than 6 mm, it is necessary to separate the material larger than 6 mm with a sieve and return it directly to the classification equipment or ball mill.This paper will discuss the advantages and disadvantages of several configuration forms of Knelson Concentrator in China for reference.

In this way, the discharged of ball mill is divided into undersizematerial and oversizematerial through a fixed sieve installed at the discharging port of ball mill. The oversizematerial goes directly into the spiralclassifier for classification. The undersizematerial is fed into the KnelsonConcentrator for gravity separation and recovery of coarsegold. The tailing of Knelson Concentrator are pumped to the classifier for classification.The configurationformis shown in Figure 3.

The advantage of this kind of configuration form is to make full use of the height difference between the ball mill and the classifier, and directly feed the large-grain ore into the classifier, which reduces the wear of the pump caused by the large-grain ore. The disadvantage is that the screening effect of minerals is unstable due to the frequent blockage of the screen hole, the amount of undersize minerals is unstable, the screening efficiency is low, and the recovery index of Knelson Concentrator is not as good as expected.(This configuration form is used in JinQu Gold Mine in HeNan Province)

This configuration can realize the recovery of coarsegold from the ore by KnelsonConcentratordirectly, and maximize the recovery rate of gravity separation. Gravity tailing ispumped tospiralclassifier for classification. However, due to the height difference between ball mill and spiral classifier, a lot of mineral processing plantscan not directly install linear vibrating screen, and result that this configuration formis not easy to achieve and has fewpractical application.

Thisconfiguration can make full use of the height difference between different equipment to realize the slurry self-flow. In this way, the use of pumps can be reduced, the process operation is simpler, the automation control can be easily realized, the sanitary conditions can be better, the recovery of coarse gold is more thorough, and the recovery rate of gravity separation is higher. When using this configuration form, it is better to use overflow ball mill grinding and install reverse winch screen at the discharging end of ball mill to avoid discharging large ore and crushed steel balls, and reduce the wear of pump, as well as ensure the better classification efficiency of hydrocyclone (This configuration form is used in YiXingZhai Gold Mine of Shanxi Province).

This configuration is to feed the concentrate of jig into Knelson Concentrator and enrich the super-concentrate. The tailing of jig ispumped to spiral classifier for classification. That is to say, the jig is used not only as separation equipment, but also for classification.When this configuration is applied in practice, the yield of the jig is enlarged and the function of the jig as a sieve is brought into play. In this way, the influence of large particles on gravity separation is solved, and the recovery rate of simple jig gravity separation is improved.

But its disadvantage is that the limitation of recovering fine coarse gold by jig prevents some of the fine coarse gold from entering Knelson Concentratorfor separation, which affects the recovery rate of gravity separation. The use of jigs increases water consumption. Sometimes concentration/dewatering must be used in order to ensure the requirements of operating conditions in the next process and make the process complicated and the operation difficult to control.

With the application of Knelson Concentrator, it has developed from one stage to two stagesKnelsongravity separation, and has been applied to the regrinding and classification process of gold concentrate in leachingoperation to recover the coarsegold, avoid the deposition loss of coarsegold in the leachingprocess and improve the recovery rate of gold.

(1) Knelson Concentratoris an excellent and efficient gravity separation equipment. Each configurationformhas its advantages and disadvantages, and the appropriate process should be determined according to actual production and site conditions.

(2) The choice of different formis determined by the ore properties of the selected minerals. In actual production,the appropriate number of gravity separation operations should be selected according to the size distribution characteristics of the target minerals, so as to improve the recovery index of gravity separation as far as possible, and realize the principle of early recovery and more recovery

(3) The selection of the Knelsongravity separation process should be based on the selection index and the requirements of the next process, to minimize the use of the pump, to facilitate operation, to facilitate automatic control, and to maximize economic benefits.
