Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other PGMs.The size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.
ChatSep 26, 2019· Sulfide Copper Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
