Chapter 15: Flotation of Copper-Lead-Zinc Ores

15.1.1 Hydrothermal Vein Deposits. The copper lead-zinc vein deposits are usually characterized by coarse-grained banded to massive aggregates of pyrite, galena, sphalerite and chalcopyrite. The bulk mineralogy is quite similar to that of strata-bound sulfide deposits, except that galena tends to be much more abundant in the vein deposit.

Copper-Lead-Zinc ores

Most often the copper minerals are floated after galena depression. Galena is depressed using sodium dichromate, sodium sulfite, polysaccharide (starch, dextrin) or even CMC. Addition rates of these depressants can be critical if any recirculating load is returned to the bulk rougher circuit. This flotation step is conducted at alkaline pH.
