The complex process for refining platinum. Image from UNCTAD. A platinum flotation circuit. In a process called flotation separation, air bubbles are blown through the mixture and carry platinum particles to the surface of the bath. The platinum-rich froth is skimmed from the bath and allowed to dry into a concentrated powder

At this point the platinum-bearing gravity concentrates shipped from South Africa join those produced in the Johnson Matthey smelting plant, and together enter the wet process refinery. Here they are treated for complete elimination of base metals, and the platinum metals are brought into solution for their separation and individual refining

Feb 28, 2018 The classical refining process is based on PGM chloride chemistry. It involves successive steps of precipitation and redissolution to purify the metals, followed by thermal reduction to metal. However, it gives a poor first time yield for refined metals and requires lengthy refining times, e.g., up to six months for rhodium [ 7 ]

A newly developed platinum and palladium refining process reduces the quantity of waste products generated per ounce recovered by 60%. All furnace and chemical exhaust fumes are processed through a scrubber system that removes all harmful particulates, cleaning
