Where Are Sulfide Minerals Found?

Sulfides occur in all rock types. Except for dissemination in certain sedimentary rocks, these minerals tend to occur in isolated concentrations which make up mineral bodies such as veins and fracture fillings or which comprise replacements of preexisting rocks in the shape of blankets.

Where are sulfide ores found?

Major nickel sulfide deposits are found in Canada, Russia, South Africa, and Australia. Oxide deposits are typically found stratified with a top layer of iron overburden. Below the iron is a limonite (hydrated iron oxide) which also contains 1–1.5% nickel, 40–50% iron, and 0.2% cobalt and other impurities.

Where is sulfide found in nature?

Hydrogen sulfide is found naturally in crude petroleum and natural gas. It is also produced through the bacterial breakdown of organic matter. Hydrogen sulfide can be produced by decomposing human and animal waste, and is found in sewage treatment plants and livestock areas.
