Floatation - magnetic - metallurgy. Because some copper oxide minerals are not tightly combined with iron, manganese, etc., it is difficult to separate them by using the magnetic separation method alone, and flotation has a good separation effect. ... the pre-selection by the gravity separation method will greatly reduce the cost and achieve ...
