SNF replacement anionic polyacrylamide used for mineral processing

In most mineral processing processes, polyacrylamides are used for settling and centrifugation. ASIAFLOC - PAM series products used in mineral processing industry, could be selected according to the using conditions or produce  according to customer's specific requirements. The polyacrylamides 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 polyacrylamide 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 polyacrylamide when we produce the  lignite or coal with high clay。We recommend our models of Asiafloc A2025 and Asiafloc N0210

2.Lead and zinc processing.Lead and Zinc  are usually in the form of sulfide, sometimes also in the presence of oxides and silicates. For different forms of existence, the separation and processing of lead and zinc requires different techniques. In the separation process of sulfide lead and zinc: the mineral is oxidized to zinc oxide. The oxide is then leached with sulfuric acid. The PH of around 5 neutral filtrate and PH of 2.5 can make all the concentrate dissolved in sulfuric acid. Some company  added a heat filter enrichment process to furtherly  improve the recovery rate. Backflow settlement system is usually used for neutral concentrated overflow purification.we recommend our models of Asiafloc A1630 and Asiafloc A1830

3. Phosphate.the main dressing method basically has the following ways: direct flotation and reverse flotation, anti - positive (positive - DE) scrubbing flotation, double reverse flotation, desliming, roasting digestion process, chemical processing, heavy medium separation and so on. During the  process of Phosphate production, it will  produce a large number of slime, waste rock, waste water, etc.,and the the water and the soilnear the mining  will be polluted , it will make the t ecological balance destruction if there is without  appropriate measures.and it will  affect local production and living. The waste water in the phosphate industry mainly comes from external drainage of mine and outdoor quarry, mineral processing wastewater, machine repair and auto repair water, life water, etc. Our company may take different measures according to the  water source  and quality  to meet the emission standards. In the process of wastewater treatment, various kinds of polymers can be used in the process of chemical production. These polymers can be used to speed up wastewater treatment and improve recycling efficiency of wastewater. T hepolyacrylamide can make the fine particles more compact during the sludge dewateringt process, Asiafloc pam can greatly reduce the dosage of the flocculating agent, tail mud rapid subsidence, dehydration, and effectively make the tail mud solid content over 60%, it is conveninent  to carry the tailing sludge to quarry for mine filling, vegetation, farming, planting, improve the land utilization.we recommend our models of Asiafloc A2025 and Asiafloc A1630

5. Bauxite. First, the minerals are crushed to less than 1mm grade,and then  Add sodium hydroxide with  high temperature and high pressure. Aluminum is dissolved in highly corrosive liquids, and other impurities of soluble aluminate are not dissolved. The gravel   along with the primary concentrated mineral slurry are removed after the process. Polyacrylamides are added to the primary concentration pool. This is a very important process of technology to get clear overflow. The bottom flow of the concentration pool , that is  the red mud will be processed by a reverse flow settlement process. In this process the aluminum in the liquid is recycled through a series of sink sinks. The polyacrylamide is then used again to facilitate rapid settlement and to obtain the required clarifying overflow.the overflow of  primary concentration with  aluminum is filtered ,after cooling (48 hours), and the hydrate of aluminum to facilitate the precipitation of the aluminum trihydrate. And the get  aluminum after filtered ,washing and calcined..we recommend our models of Asiafloc—CF8660 Asiafloc-CF8823 and Asiafloc-CF8950

6.Copper. The mineral can be separated from waste materials or pulsates through crushing g, and the mineral is crushed again, then be pulverized again with a ball mill or agitator. The ultimate mineral particle size is usually less than 100um. In the final crushing process, add the collector to the pulp. The collector can absorb copper sulphide and make its particles hydrophobic. The copper mines will be recycled through flotation processes. In flotation the air will be passed into the pulp. The foaming agent will also be added to produce bubbles and make the copper particles firmly attached to the bubbles at the top of the pulp. The slurry or tailings from the flotation pool will be into the enrichment pool for further settlement. At this time,Thepolyacrylamide is added to facilitate rapid settlement and produce  overflow. Clarification of overflow will be used as circulation water. The remaining concentrated tailings will be centrifuged dewatering, and the polyacrylamide will be added as a centrifugal additive. The bubbles (concentrates) which  with copper  are separated from the overflow  by  mechanical method. Then it is concentrated and dehydrated. The polyacrylamide is used to improve the efficiency of settlement and filtration. The final refined mining  or filter cake contains nearly 25 to 35 percent copper. This will be recycled through high temperature metallurgy.we recommend our models of Asiafloc A1630 and Asiafloc A1630A
