Extraction of Platinum Group Metals IntechOpen

Feb 21, 2018 1. Introduction. Platinum group metals (PGMs) are a group of six elements, namely iridium (Ir), osmium (Os), platinum (Pt), palladium (Pd), rhodium (Rh) and ruthenium (Ru) [1, 2].PGMs together with gold and silver are classified as noble or precious metals because of their high corrosion and oxidation resistance [1, 2, 3].The world’s reserves of platinum group metals/elements are

Sources & Extraction Iridium

Iridium is naturally found by itself as well as in alloys. It is found in igneous deposits, impact craters, and meteorites. The biggest sources of iridium are located in South Africa, Russia, and Canada. There are some small concentrations of iridium in the U.S. Iridium is mined from the earth, then separated from other metals if it is in an alloy.
