Despite the fact that pyrite is a relatively common phase in Ni-Cu-Platinum-Group Elements (PGE) magmatic sulphide deposits, the trace element content of the pyrite has been neglected in the studies of these deposits with most attention being paid to the PGE concentrations of pyrrhotite, pentlandite and chalcopyrite.

Platinum : Properties, Uses, Occurrence and Localities

Formation of Platinum: Magmatic Processes: The primary source of it is magmatic ore deposits, which originate from the cooling and solidification of molten rock (magma) deep within the Earth's mantle and crust. These deposits are associated with igneous rocks and are known as "platinum group element (PGE) deposits." PGEs, …

Platinum-group elements in porphyry copper deposits: a

Sulphide and flotation concentrates from 33 porphyry copper deposits have been investigated for platinum-group elements (PGE), Au, Cu and platinum-group minerals (PGM). The major sulphides in the samples studied are chalcopyrite and pyrite. Bornite is less frequent and molybdenite occurs in traces only. PGM (merenskyite, sperrylite and …
