Flotation Reagents - Mineral Processing & Metallurgy

The most widely used sulphidizer is sodium sulphide, which is commonly used in the flotation of lead carbonate ores and also slightly tarnished sulphides such as pyrite and galena. In the sulphidization of ores containing precious metals careful control must be exercised as in some instances sodium sulphide has been known to have a depressing effect on flotation of metallics.

Copper extraction - Wikipedia

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.
