In the mining industry, effective separating the mineral solids from water or aqueous solutions is critical. If there is no effective flocculation in sedimentation or centrifugation process, the heavier inorganic solids may fall to the bottom of the settler and the smaller particles will be suspended in the supernatant, such as the standing solution. Then the efficiency of filtration and dehydration is also significantly decreased by the existed of small amounts of particles in the supernatant. While these small particles can be quickly settled down by adding Polyacrylamide (PAM) to this aqueous dispersion, in this process the individual particles in the suspension tend to aggregate to form heavy aggregates easily and settle very quickly and the upper dispersion becomes a clear liquid. Coal Washing The active groups on the polyacrylamide molecular chains of coal washing adsorb on the surface of the fine particles in the slime water, which connect the particles and make the fine pa...

Sinofloc Polyacrylamide is commonly used in concentrate dehydration, accelerated frame mud settlement, purification and improving the efficiency of the dense machine in the mining field. Selective flocculation of the pulp of fine-grained minerals is also a key application of our polymers, which could change the surface characteristics of the target mineral particles to increase the particle size, and thus flocculate and precipitate. In addition to the flotation, our polyacrylamide polymers could be used in the waste water treatment. The mine wastewater is generally the acidic state of iron, manganese, copper, gold, zinc ore. The treatment of such waste water is generally used neutralization method, which will adjust its PH value, the most commonly used limestone, and lime to do the regulator. For example, after the iron ore wastewater is neutralized, the main components of the waste water are iron hydroxide Fe (OH) 3 and colloid, Ca (OH) 2 calcium hydroxide and colloid, Fe (OH) 2 ferro...
