Extraction of Platinum Group Metals | IntechOpen

To separate the PGM-rich sulphides from the gangue minerals, smelting is used. Rectangular six-in-line or circular three-electrode electric furnaces are typical in the PGM industry [ 12 ]. Smelting is a high-temperature process step where the sulphides (valuable minerals) are separated from the silicates (gangue minerals).

Graphite - chemeurope.com

Graphite (named by Abraham Gottlob Werner in 1789 from the Greek γραφειν (graphein): "to draw/write", for its use in pencils) is one of the allotropes of carbon.Unlike diamond, graphite is an electrical conductor, and can be used, for instance, in the electrodes of an arc lamp. Graphite holds the distinction of being the most stable form of solid carbon ever discovered.
