In the metal metallurgy field, whether it is the initial mineral processing or late refining process, a solution as a reaction carrier will be used, and the enrichment of minerals will be deposited to obtain high concentrations of metal compounds through solid-liquid separation. In this series of complex mineral processing, enrichment and separation process, various additives are needed to strengthen and improve the settlement, solid-liquid separation efficiency. For a variety of mining and metallurgical industry, Sinofloc developed a series of polyacrylamide products, which has good application in gold and silver precious metals smelting, alumina industry, iron and steel smelting, zinc/ copper/ lead smelting and other areas of mineral separation problems. Through using different models of polyacrylamide, the solid-liquid separation and effect of enrichment could be greatly improved in the process of beneficiation, tailings flotation, concentration and sedimentation, washing sediment...
