The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.

chapter 11 applications of ore microscopy in mineral technology

The McArthur. River Deposit (Figure I1.1a) is large (>200 million tons) and rich (>9% Zn), but it contains much ore that is so fine grained that conventional processing cannot effectively separate the ore and gangue minerals. Consequently, the deposit remains unmined until some other technology is available that would.
