Smelting of the concentrate produces a matte that is leached of copper and nickel sulfides in an autoclave. The solid leach residue contains 15 to 20 percent platinumgroup

THE PRIMARY PRODUCTION OF PLATINUM GROUP METALS

The six platinum group metals (PGMs) occur together in nature alongside nickel and copper. Mineable deposits of PGMs are very rare, with annual production amounting to around 400 tonnes, several orders of magnitude lower than many common metals. Due to their economic values and higher quantities, platinum and palladium are the most

Rare Earth Metals From Asteroids Astronomy Source

Platinum group metals. Platinum group metals do not occur naturally in the Earth''s crust, but are present due to earlier meteorite impacts. A meteorite is simply a piece of asteroid which has fallen to Earth, so the study of meteorites gives geologists a good idea of the most suitable types of asteroid to choose as candidates for mining.

Concentration of Platinum Group Elements during the Early

Numerous unique geological processes [1] took place during the early Earth evolution several of them, especially those occurring in the Hadean—Early Archean and later, are reflected in the modern geological (geophysical, geochemical, etc.) pattern.
