centers for the enrichment of ore lead

Ore deposits formed by oxidation and supergene enrichment

Secondary enrichment of porphyry copper deposits in the southwestern United States, Mexico, Peru, and Chile is an important factor in making those deposits ores. Lead, zinc, and silver deposits are also subject to secondary enrichment under conditions of desert weathering. 3.

Supergene geology - Wikipedia

Supergene enrichment occurs at the base of the oxidized portion of an ore deposit. Metals that have been leached from the oxidized ore are carried downward by percolating groundwater, and react with hypogene sulfides at the supergene-hypogene boundary. The reaction produces secondary sulfides with metal contents higher than those of the primary ...

Lead and Zinc -

Lead Ore The lead produced from lead ore is a soft, flexible and ductile metal. It is bluish-white, very dense, and has a low melting point. Lead is found in veins and masses in limestone and dolomite. It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is

Mining and enrichment KGHM Corporate Website

Copper and silver are indispensable natural resources for the development of global economy. During 60 years of company& 39;s activity, KGHM has extracted over a billion tonne of mining output and has produced 20 million tonnes of copper. Current deposits will suffice for the next 40-50 years of mining activities. The copper ore deposit operated by KGHM in Poland dips monoclinally at the depth ...

…the ore mineral of lead, galena. Its highly symmetric form consists of cubes modified by octahedral faces at their corners. The structure of the common sulfide pyrite FeS 2 also is modeled after the sodium chloride type; a disulfide grouping is lo ed in a position of coordination with six surrounding ferrous…

Polymetallic replacement deposit - Wikipedia

When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly called a manto ore deposit. Other ore geometries are chimneys and veins. 4 Polymetallic replacements/mantos are often stratiform wall-rock replacement orebodies distal to porphyry copper deposits, 5 or porphyry molybdenum deposits 6 .


ore formation is a common and intrinsic part of crustal evolution, large and super large ore deposits require the coincidence of particularly favourable combinations of processes and source parameters. This brief review outlines the key primary geochemical expressions of the main metalliferous ore deposit types found in Australia. To a large
