Is platinum a metallic minerals?
Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth’s crust.
What kind of minerals are found in platinum?
It is always associated with small amounts of other elements such as iron, gold, copper, and nickel, and may also contain the rare metals iridium, osmium, rhodium, and palladium. These impurities can lower its specific gravity to as much as 14, whereas pure elemental platinum is 21.4.
What are the properties of platinum group metals?
They regarded platinum as an unwanted impurity in the silver they were mining. The catalytic properties of the six platinum group metals (PGM)– iridium, osmium, palladium, platinum, rhodium, and ruthenium – are outstanding. Platinum’s wear and tarnish resistance characteristics are well suited for making fine jewelry.
Where does platinum and palladium ore come from?
PALLADIUM ORE AND PLATINUM ORE Platinum is a very rare metal, occurring only in trace concentrations in the Earth’s crust. Platinum occurs as the native metal, although that form now constitutes only a small source of the metal. Most platinum is recovered from primary hard rock deposits, and these are of the greatest economic importance.
Where can you find platinum in the world?
Platinum is found in its pure native form, or in platiniridium, a natural alloy of platinum and iridium. Platinum is present in thin sulfide layers in certain maficigneous bodies and is mined in Canada, Russia, South Africa, the USA, Zimbabwe and Australia.
