Gold and silver are very good conductors of electricity and heat. Gold, copper and silver can be alloyed (mixed) with other metals to produce new materials. Gold, copper and silver are malleable – they are easily shaped, and very ductile – they can be stretched out into very thin wires. Gold and silver do not chip, flake or corrode.

Copper extraction

Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

copper processing

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves. The amount of copper in an ore can .

Copper Ore

Copper ore usually contains about to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.

Copper Mining Using Acidothiobacillus

In situ biomining does away with the ore mining process altogether; acidified leach liquor is pumped directly into the ground and the copper is solubilized utilizing preexisting bacteria in the ore deposits. The copperrich liquor is extracted from wells dug beneath the deposits (Rawlings 2002). By eliminating the physical act of ore mining, a significant portion of the costs is cut .
