In most mineral processing processes, flocculants are used for settling and centrifugation. SIMO series products used in mineral processing industry, could be selected according to the using conditions or produce according to customer's specific requirements. The flocculants are optimized according to the types of mining, and our products and services are introduced in the field of beneficiation.
1.Once the coal is extracted, it is classified according to the grain size and then separated from the water according to the difference in the gravity of the coal and impurities in the medium of water. The coal floats on the top of water , the impurities sink to the bottom, and the processed coal is then sorted again to get the final product. In the process, a fine powder coal is produced, which requires further processing and recycling. This process is usually carried out by flotation methods, with flotation reagents to improve the separation efficiency of coal and impurities. Refined Coal is flotated , and the tail coal is setting down. The refined coal is recoveried through settled, filtered or centrifuged . The flocculant is applied in the settlement process to promote the separation of solid liquid. Then in the concentrator, water is recycled by the overflow of the concentrator. The powder coal is filtered and centrifuged. The efficiency of the separation process is improved by adding coagulant before adding the flocculant when we produce the lignite or coal with high clay,.
2.In the process of gold and silver washing,。the method of carbon slurry or carbon filter is generally adopted. Use activated carbon dissolved in cyanide to recover gold and silver. Before filtering, the ore is crushed and screened, and the selected minerals are added to the ball mill to add water and lime. Adding flocculant to each concentrator promotes the rapid deposition of solids and filters through a series of filters. So gold and silver have enough time to dissolve in cyanide. The gold and silver is extracted from the solution by a series of carbon adsorption slots, and in the negative direction of slurry , put the activated carbon in it and the gold and silver are sticked on the carbon particles and be extracted from the carbon particles. Most of the gold and silver have been extracted before the pulp reaches the last sink. Pouring the remaining pulp into the sink, where the carbon particles arrive at the first sink, which has absorbed most of the gold and silver in the solution. The carbon particles with rich gold and silver are delivered to the washers, and gold and silver are flushed from the carbon particles with ultra-hot water. The solution containing gold and silver is collected through the electrolytic pool.
