The content of platinum group metals (PGMs) in proterozoic platinum ores is about 1–10 g/t, while in Cu–Ni sulfide ores containing PGMs, the content is only 0.1–1 g/t. By flotation, the content of PGMs is concentrated to more than 100 g/t.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

Flotation of Platinum Group Metal Ores concentration of chromite and with alpine ultrafamic bodies. As a process of weathering, there is a marked change in Pt/(Pt–Pd) ratio as compared to the source becoming greatly increased in the former due to the greater ease with which Pd dissolves and is removed in a weathering enrichment.

Platinum group metals (PGMs) are characterised by numerous applications, of which catalysis is most meaningful. However, raw material situation is critical due to global demand and their high geographic concentration of deposits, combined with the generally rather low content of ~ 3 g/t (10 g/t in rich ores) ( Bertau et al., 2016 , Neukirchen and Ries, 2014 ).
