The gold in the veins may be of microscopic particle size, in nuggets or sheets, or in gold compounds. Regardless of how it is found, the ore requires extensive extraction and refining. One third of all gold is produced as a by product of copper, lead, and zinc production. Copper, for example, must be electrolytically refined to raise its
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living.
Copper (Cu) is a ductile metal with very high thermal and electrical conductivity. It is of reddish colour and has the second highest electrical conductivity after silver. Copper is easily worked as it is malleable. Native copper can be found in alluvial deposits, granitic and basaltic rock.

One third of all gold is produced as a by product of copper, lead, and zinc production. Copper, for example, must be electrolytically refined to raise its purity from 99% to more than % as required for many industrial
Emeritus Professor Ken Collerson observed that because the REE (and Co) may be recovered as a byproduct of the coppergold concentration process at Kalkaroo This could potentially provide an economic advantage for the Kalkaroo project, compared to those projects that are solely REE further notes that Kalkaroo is advantaged in having the highest proportion of the more valuable heavyREEs.
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
#0183;#32;Global mine production of copper is estimated to have exceeded 19 million metric tons in 2017. The primary source of copper is Chile, which produces approximately onethird of the total world supply. Other large producers include the US, China, and Peru.

Actually, there is little to no reaction of vinegar on copper metal (hence, the copper wire in solution is clear). Existing ce{Cu2O} coating will be slowly attacked, forming a cuprous acetate which in air/oxygen creates soluble cupric acetate. The latter serves as a weak electrolyte for a further electrochemical attack of the copper metal with ce{O2} subject to an inception period delay.
#0183;#32;Production . Copper is typically extracted from oxide and sulfide ores that contain between and percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is extracted from sulfide sources.

AIMlisted gold and copper explorer and developer KEFI Gold and Copper is well on its way to begin development of its Moz Tulu Kapi gold project in Ethiopia. KEFIs subsidiary, Tulu Kapi Gold Mines Share Company (TKGM), is a public private partnership
#0183;#32;However, if the miner is specifically focused on finding gold, the byproduct metals can make it hard for investors to get a clear picture of the company''s current production profile compared

Mines where the byproduct makes up a significant amount of production by revenue or even a majority can drive the costs into negative numbers. Thats the case at New Afton, where the 25,300 ounces of gold mined in the fourth quarter generated about 30million in revenue, using New Golds average realized price of 1,188 per ounce.

#0183;#32;From a current gold world production of approximately 2,600 tonnes, about 10% is recovered as a byproduct (Chen and Dutrizac, 2004). Most of it is recovered as a byproduct from the copper industry, but significant quantities of gold are also recovered as a byproduct from the nickel and lead industry, and the potential also exists to recover gold as a byproduct from the zinc and cobalt
