Sphalerite | Article about sphalerite by The Free Dictionary

Sphalerite. It is formed in hydrothermal deposits together with galena, pyrite, chalcopyrite, arsenopyrite, quartz, calcite, barite, and dolomite and in sedimentary deposits. In the zone of oxidation, sphalerite alters to zinc sulfate (goslarite) and smithsonite. Sphalerite is an important zinc ore.

The Enhancement of Galena Flotation Using Cyanide AusIMM

Cyanide has been variously described as an iron sulphide depressant, a preventor of sphalerite activation and as an activator of galena. In the case described here, the cyanide appeared to act as an enhancer of the galena flotation performance, raising the lead recoveries by 25 per cent but leaving the sphalerite and pyrite responses unaffected.
