Lead-zinc Processing
Lead-zinc ore is rich in metallic element: lead and zinc. Lead and Zinc is widely used in electrical industry, machinery industry, military industry, metallurgy industry, chemical industry, light industry and pharmaceutical industry, etc. In addition, the Lead is of great use in the department of nuclear industry and oil industry. Lead is the earlier metal that human refined from lead-zinc ore. It is the most soft metal, and is one of the big specific gravity metals. It is blue-gray, 1.5 hardness, specific gravity 11.34, melting point 327.4 ℃, boiling point 1750 ℃. It is very malleable, easily made to alloy with other metal (such as zinc, tin, antimony, arsenic, etc.).
The complete set of equipment for Lead-zinc ore dressing mainly contains: Jaw Crusher, Hammer Crusher, Impact Crusher, Vertical Shaft Impact Crusher, high-efficiency and energy-saving ball mill with conical bearing. Vibrating Screen, Auto-reverse sand spiral classifier, high-efficiency and energy-saving flotation machine, mining agitation tank, feeder, thickener, mine hoist, mine conveyor, adding water into a ball plate, spiral chute, mining table, washing machines and other equipments.
There are three types of lead-zinc beneficiation technology:
1. Crushing, Grinding, Classify, Flotation Selection;
2. Crushing, Grinding, Gravity Separation;
3. Crushing, Screening, Roasting.
Lead and zinc recovery rate is 90%.The lead powder is about 75% and zinc powder is about 45%.
