Namib Lead & Zinc Mining

Historically, the mine produced approximately 700,000 tonnes of ore (calculated from the company''s 3D models of the mine voids), producing over 100,000 tonnes of lead and zinc concentrate, and over 1,000,000 ounces of silver. After net smelter returns, this would have yielded revenues in excess of US$100 million at current commodity prices.

How to Process Copper Lead Zinc Ore with Gold and Silver ...

 · The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.

Lead and Zinc

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Lead Mining – Concentration process, flotation, filtering ...

Lead is extracted from ores dug from under-ground mines. Lead is also found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by- product of these other more valuable metals. Extracting the lead materials from the ore is a tedious process. First the lead ore is ground into small salt-like particles.

Reclamation of Mine Lands in Poland

 · Nonferrous metal industry, i.e., copper, zinc, and lead produces a large amount of waste. Low metal content in the mined ore means that waste from the ore enrichment process constitutes 80%–90% of the total amount of processed material. The mining of these ores results in geomechanical, hydrological, and chemical transformations.
