Zinc processing | Britannica

The flotation performance of a complex lead and zinc ore were investigated by changing the grinding environments. Four groups of testing were conducted with different depressants or their combinations. Flotation results, size-by-size analysis, pulp potential (Eh) and dissolved oxygen (D0) were studied. It was found that the addition of depressants during grinding was beneficial to increasing ...
