What are sulphide ores?

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.
