Flotation Regulator: Inhibitor - JXSC Machine
Sodium sulfide is used as an inhibitor of sulfide ore in flotation operations. In the production practice of molybdenum separation, sodium sulfide is used to inhibit pyrite, and kerosene is used as a collector to flotation molybdenite. The buoyancy is good and is not inhibited by sodium sulfide. Sodium sulfide inhibits pyrite.

Pyrite - an overview | ScienceDirect Topics
Pyrite oxidation begins with the oxidation of sulfur by oxygen yielding sulfate, ferrous iron, and acidity. The rate-limiting step is the oxidation of Fe 2+ to Fe 3+, which occurs only very slowly at low pH chemically, but is catalyzed by bacteria that speed up the reaction rate by a factor of 100 000. Once underway, the process of pyrite oxidation may continue until the source is exhausted.
