Pyrite - Wikipedia

The mineral pyrite , or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. 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 invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydro- metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.

TACKLING IMPURITIES IN COPPER CONCENTRATES

Concentrate “A” has the sulphides being mostly chalcopyrite and some pyrite and a higher gangue fraction. Concentrate “B” distributes its copper mostly between chalcopyrite and tennantite and has considerably more pyrite. The mercury mineralogy for the two concentrates was quite different as shown in Table 5:
