2019-10-9  The chalcopyrite and pyrite losses in the tailing from the rougher circuit were the same for both bulk and sequential roughing (less than 6%). In cleaning (bulk circuit), the effective pH for pyrite depression was about 11.8. The copper recovery was 70% (grade of 20% copper) and the sulfur recovery (pyrite product) was 80% (grade of 36% sulfur).

Copper-Lead-Zinc ores - Danafloat

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.
