207-173-7 Flocculant Polyacrylamide For Mineral Processing Industrial Water Treatment

Tin Flotation Flocculant Anion Polyacrylamide

At Jiangsu Hengfeng Fine Chemical Co. Ltd., we specialize in producing high-quality polyacrylamide (PAM), can be applied in the mining,processing and tailing disposal process of mines such as coal, gold, silver, copper, iron, lead and zinc, aluminium, uranium, nickel, phosphorus, potassium, manganese and other minerals.Its main purpose is to improve the efficiency of the solid-liquid separation and recovery rate.

Copper Mining
The pulp or tailings from the flotation cell need enter into thickening tank for further settlement. Flocculant can be fed for the promoting of subsidence and obtaining of overflow. The gained overflow can serve as circulating water.The remaining concentrated tailings will be pumped into the centrifugal for centrifuge dewatering,in which anionic polyarylamide as centrifugal additives is utilized. Anionic polyacrylamide flocculant is used to improve the efficiency of sedimentation and filtration. The concentrate of copper gained from cleaned mine or filter cake is 25% to 35%. It will be recovered through high temperature metallurgy.

Coal Washing
Flotation process is usually adopted to gain cleaned coal with high combustion value.Since the difference in proportion between coal particle and impurity in water,coal mine will float on the surface of the water while the impurity will percipitate at the bottom of the container.Cleaned coal is obtained after further process.In the above process,impurity can be removed and water can be recycled.Polyacrylamide can function as a flocculant to improve the seperation efficience of water and impurity.

Nickel Mining
In the "wet" process,feeding PAM can get a quick water-mud separation effect when separate nickel from nickel mine.

Lead and Zinc Mining
Minerals can be oxidized to zinc oxide by calcination.Next,feed sulfuric acid to dissovle the oxide and filter.All the cleaned mines can be dissolved in acid with PH around 5 or 2.5.In lead and zinc filtering process, the use of anionic polyacrylamide flocculant can effectively promote the rapid subsidence of mineral and the clarification of the filtrate and improve the production efficiency of the process, reduce the loss of minerals.

Gold and Silver Mining
After the mine is grinded, anionic polyacrylamide flocculant can be fed to the thickener to subside the Solid content(%),and then the bottom substance can be filtered through several filters.Add polyacrylamide to the thickener before the filtration.
