Supergene-enriched copper ore was found primarily above the 300-foot level of the old Copper Canyon underground mine and was composed of primary copper-gold ore plus secondary chalcocite and minor native copper. The grade of this enriched ore averaged nearly 10% Cu, five times that of the primary ore. The copper-enriched zone …
Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. It is a common …
Galena crystals surrounded by marcasite, from Shullsburg, Wisconsin. (Photo by W. Cordua.) Galena is formed in a wide range of hydrothermal environments. It can be found with sphalerite and chalcopyrite in massive sulfide deposits associated with meta-volcanic rocks, such as the Crandon deposit near Rhinelander. It is a component of some …
lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy castability and softness and malleability, make ...

Leaching gold in Calcine. The principal cyanides in the calcine are copper, ferrous iron, and smaller amounts of Mo, Co, Ni, Mn, etc. Most of the cyanicides can be removed by water washing, but this step cannot be used owing to the loss of about $0.70 in gold resulting from the use of salt in the roast.
Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold. The most common lead-ore mineral is galena, or lead sulfide (PbS). Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate (PbSO4). Cerussite (PbCO3) is a mineral that is a carbonate of lead. All three ...

In the traditional view, supergene ore and gangue minerals are the products of reactions between hypogene sulfide minerals and descending, acidic meteoric waters; these processes take place at or near the ground surface in subaerial environments (Guilbert and Park, 1986). In VMS deposits, copper and other metals are mobilized from primary massive
