Elements: Platinum group | SpringerLink
Chemists refer to the six heaviest elements in group VIIIA: Ru, Rh, Pd, Os, Ir, Pt; as platinum metals ( Cotton and Wilkinson, 1966 ). However, since the mid-1960s geologists have used the expression platinum-group elements (PGE) to refer to these elements. In igneous rocks Au and Ag frequently behave in a similar manner to the PGE, and the …

Platinum-Group Elements—So Many Excellent Properties
The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have similar physical and chemical properties and occur together in nature. The properties of PGE, such as high melting points, corrosion resistance, and catalytic qualities, make them indispensable to many industrial applications.

Platinum group metals (PGMs) are recovered using molten Cu or Pb as collector metals during pyrometallurgical recycling processes. The collector metal containing PGMs is oxidized to produce a PGM-enriched alloy and slag, primarily containing Cu or Pb oxide. Additionally, the slag comprises a considerable amount of PGMs. Therefore, it is …

Distribution of platinum-group elements in magmatic and
The division of platinum-group elements (PGE) between those hosted in platinum-group minerals (PGM) versus those in solid solution in base metal sulfides (BMS) has been determined for ores from the PGE-bearing Ni-Cu-rich Jinchuan intrusion in northwest China. All the BMS are devoid of Pt and Ir, and magmatic BMS are also barren …
