Identification and Description of Mineral Processing

2016-3-27 Cadmium is mainly a byproduct of the production of zinc metal from sulfide ore concentrates. The mined zincores are crushed and ground to liberate the zinc sulfide particles from the waste host rock. The ground ore is usuallytreated by a differential flotation process to separate the zinc-bearing particles from the waste rock, yielding a high-gradezinc concentrate and waste tailings. About 90% to 98% of the cadmium present in zinc ores is recovered in the miningand beneficiating stages of the extraction process. Zinc concentrate is converted from zinc sulfide to zinc oxide byroasting, and at the same time most of the sulfur is removed as sulfur dioxide. The sulfur dioxide offgas is stripped of allentrapped dust and other impurities and then converted to sulfuric acid in an acid plant.4 Cadmium is recovered fromzinc and zinc
