Technological Process of Lead-zinc Ore Dressing
Lead zinc ore has a rich content of metallic element lead and zinc. Lead zinc ore has a wide application in electric industry, machinery industry, military industry, metallurgy industry, chemical industry, light industry and medical industry. Besides, lead metal has multiple purposes in oil industry. Lead is one of the metals extracted from lead zinc ore. It is one of the most soft heavy metal, and also with big specific gravity, blue-grey, hardness is 1.5, specific gravity is 11.34, melting point is 327.4℃, boiling point is 1750℃, with excellent malleability, it is easy to be made into alloy with other metal (such as zinc, tin, antimony, arsenic, etc).
Complete set of equipment for lead-zinc ore dressing include: jaw crusher, hammer crusher, impact crusher, vertical shaft impact crusher, high efficient cone bearing ball mill, vibrating feeder, auto spiral grading machine, high efficient energy conservation floatation machine, mining agitation tank, vibrating feeder, thickener, mining elevator, mining conveyor machine, spiral chute, ore washer, etc.
Generally, there are three kinds of technological process for lead zinc ore dressing:
1, crushing, grinding, grading, floatation;
2, crushing, grinding, re-selection;
3, crushing, screening, roasting.
