Mineral processing operators use equipment to process mineral ores until the final form or a concentrate is produced. Commonly processed minerals include gold, silver, nickel and iron ore. Mineral-bearing ore is subjected to various processes to extract the minerals. The ore is first crushed, then processing equipment (such as screens, grinding mills, filters, flotation cells, tanks and conveyors) is used to extract concentrated minerals. At the end of the treatment process the minerals may be produced into their final form by smelting, or as a bulk concentrate in preparation for shipment from site.
