A method of electrowinning or electrorefining copper from a copper electrolyte solution which contains chloride ions, the method comprising the steps of: (a) forming a polyacrylamide solution by dissolving polyacrylamide, having a molecular weight range of 5,000 to 20,000,000 Daltons, in an acidic medium and under conditions to form a polyacrylamide block copolymer having blocks of carboxyl groups .
Introduction to Mineral Processing
froth flotation cells. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.
