Refiners and Smelters of PGMs (Platinum Group Metals)

Platinum group metals (PGM) are refined using highly sophisticated chemical methods that are particular to their composition. The use of the right compounds, as well as the chemical reactions that occur, makes it easier to separate PGM from other elements that may be attached. Refining is the process of purifying an impure metal in Concentrators are also used for precious metal separation from aggregate or placer deposits. The target mineral will usually be in extremely low concentration (grams per tonne) and a very high upgrade is desired (up to 10,000x). Reliable test work can lead you to the right concentrator for your application. Sepro operatesCOARSE AND FINE PRECIOUS METAL RECOVERY Sepro
