Introduction of Lead and Zinc Ore. Lead is one of the earliest metals which were extracted from lead-zinc ore by humans. It is one of the soft metal, with blue-gray, hardness 1.5, specific gravity of 11.34, melting point 327.4 ℃, boiling point 1750 ℃, good ductility, which is can be easy made of alloy with other metals such as zinc, tin, antimony,arsenic, etc. Zinc is the last one in the

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as
lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of
4 Mining & Mineral Processing Milling There are many types of process machinery to reduce the size of the ore and allow it to pass through to the next stages. These are found in both the primary and secondary milling stages. Some are high pressure grinding mills, autogenous and semiautogenous (SAG) mills, cone crushers and ball mills.
The Namib Lead & Zinc team obtained and reviewed legacy information relating to the operations of the mine from 1968 to 1991. This includes diamond drill data that was conducted during that period and before operations commencing in 1969.
