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.
