Magmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without (±) platinumgroup elements (PGE), account for approximately 60 percent of the world's nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions.

Nickel sulfide deposits are generally associated with iron and magnesiumrich rocks called ultramafics and can be found in both volcanic and plutonic settings. Many of the sulfide deposits occur at great depth. Laterites are formed by the weathering of ultramafic rocks and are a nearsurface phenomenon.

25/06/2021 · Palladium is also an exchange traded metal (along with platinum, gold and silver) Ruthenium and Rhodium Both ruthenium and rhodium are byproducts of other PGMs and coppernickel ores, with tiny production figures. Ruthenium is used to harden platinum and palladium alloys to make highly resistant electrical contacts.

Gold sometimes occurs as a lode deposit in small amounts in rock, known as gold ore. Gold can also be found in alluvial deposits known as placer deposits, as flakes, grains, or nuggets. Ore, a naturally occurring rock or sediment with enough minerals, must be considered economically important enough to extrie. Ores can be either metals or gems.
