Pyrite - Wikipedia

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

Lime use in gold processing – A review - ScienceDirect

The tails from this process report to the pyrite flotation circuit where pyrite is reactivated (i.e. the depression effect is reversed so that it will float), typically using potassium amyl xanthate (PAX). The gold-containing pyrite concentrate then reports to the cyanidation circuit for gold leaching and recovery (Benson et al., 2007; Akop, 2014).
