MINING Gold is obtained by two principal mining methodsplacer and vein miningand also as a byproduct of the mining of other metals Placer mining is used when the metal is found in unconsolidated deposits of sand and gravel from which gold can be easily separated due to its high density, In the refining process an anode of impure.
The mining process ore processing ore processing at the processing plant gold and silver are extracted from the ore where it is further refined to separate the gold from the silver after refining the gold and silver is credited to the oceanagold mint acc,Comercial Gold Mining Refining Process.
Generally, gold can be refined using these twobestknown goldrefining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
9 Step Process for Discovering, Mining amp; Refining Gold. By ProvidentMetals on January 23, 2012 Filed Under: Uncategorized. Weve no doubt all seen the old western movies of the prospector with a pan in the river searching for gold. Mining for gold today can essentially be broken down into 9 steps.
The gold is separated from the cyanide solution and smelted to remove some of its impurities. The molten gold, called crude bullion, is then cast into molds. The gold is further refined into pure material by electrolytic refining, chlorination, or acid leaching processes.
#0183;#32;More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidized and dissolved in an alkaline cyanide solution. The oxidant employed is atmospheric oxygen, which, in the presence of an aqueous solution of sodium cyanide, causes the dissolution of gold and the formation of sodium cyanoaurite and sodium hydroxide, according to the socalled Elsner

Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved. Then, we have two smelt and cast the gold into bars called bullion or Dore. The name bullion is restricted to the precious metals, refined or unrefined, in
#0183;#32;The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have
The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
The result of this process is percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell. The refiners will then pass an electric current through the cell. At the end of this process, the gold will be percent
