The flash smelting process is important in the production of non-ferrous metals from sulfide minerals. A schematic diagram of this process is given in Fig. 7.17. In this process, fine, dried mineral particles and fluxes are injected into the furnace with industrial oxygen or oxygen-enriched air. The sulfide particles are ignited and burn in the ...
Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities. Gold is often associated with PGM deposits and treated as part of a family — with Platinum, Palladium and Rhodium —collectively known as "4E".
