Polyacrylamide is widely used in mineral processing fields such as gold,silver,copper,aluminum,lead,and  zinc.In  these processes,a large amount of water is required to effectively separate mineral solids from water or aqueous solutions. The use of polyacrylamide as a flocculant or filter aid can promote the rapid sinking of useful solid minerals,accelerate the concentration of fine materials,and improve filtration efficiency,thereby increasing efficiency,improving separation and production efficiency,

reducing tailings loss,and reducing costs.
