1. Lime Method. Lime is a common inhibitor of pyrite. When using the lime method for copper-sulfur separation, the pH value of the pulp or the free CaO content in the pulp can significantly affect the separation effect.The general rule is that a pH value of about nine can float copper and suppress sulfur when dealing with dense iron ore with a large amount of pyrite …
