Some recycling facilities re-smelt and recast non-ferrous materials; the dross is collected and stored onsite while the metal fumes are filtered and collected. While the mineral endowment of platinum in South Africa is relatively abundant, investment in new supply sources for platinum has dwindled over the past decade as platinum demand weakened resulting in oversupply and depressed prices. They possess individual properties that make them uniquely attractive for certain uses in highly developed technology and for use in jewelry and for decorative purposes. Sulfur reacts and forms compounds with all elements except gold, iodine, iridium, nitrogen, platinum, tellurium, and the inert gases. It is part of the refractory metals group, which are widely used as minor components in alloys.
