DEFINITION OF SULFIDE MINERALS

Many of the ores of metallic minerals

occur as compounds of the sulfide ion, S2–, with the metals

attached as cations. Most of these are soft and look like metals

and form many of the world’s large ore deposits. One of

the most common sulfide minerals is pyrite, FeS2, found as a

minor component in many rocks and as an accessory mineral

in many ore deposits. Pyrrhotite (Fe7S8–FeS) is a less-common

iron sulfide mineral. Most ore deposits are formed from

hydrothermal fluids. Lead (Pb) and Zinc (Zn) are commonly

found in sulfide compounds such as galena (PbS) and sphalerite

(ZnS), and copper deposits are dominated by the two

sulfide minerals chalcopyrite (CuFeS2) and bornite (Cu5FeS4).
