Bilder von extraction of gold by cyanide process
Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
Cyanide Process - Gold Cyanidation Process | …
Cyanide Process – Extraction Of Gold Through Cyanidation. Gold is usually found in low concentration in the form of ore which is mined. Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold.
Process of Cyanide Gold Extraction
When other constituents of the ore besides gold are competing for the available CN ions, gold extractions would be affected adversely. By the reaction of such CN ions, to form thiocyanate for example, the ratio of total cyanide to copper would drop and the equilibrium of the sodium cuprocyanide would be affected.

The Metallurgy of Cyanide Gold Leaching – An …
Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
Cyanide Chemistry & Gold Extraction
The fact that many millions of gold have been extracted by the cyanide process, during the last five or six years, from South African tailings which could not be profitably worked by any other method previously tried upon them, lends a peculiar practical interest to this branch of metallurgy.
Extraction of Gold
Concentration is effected by washing, and the " concentrates " are chlorinated by the Plattner process. A further operation divides the waste products into 60 per cent, of " tailings " and 40 per cent, of "slimes," and these materials are further extracted by the cyanide-process.

Gold Extraction / Mining | Gold.info
Extraction of Gold by Cyanide Leaching. The process of cyanide leaching is mainly used where the earth has a high gold concentration making an industrial development worthwhile. For this process the gold-bearing rock is crushed to sand and dust. Subsequently, the rock dust – piled in heaps, columns or stored in tanks – is combined with a ...

Cyanide Leaching Of Gold - Mine Engineer.Com
Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890s, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.
Extraction of gold using cyanide - NZQA
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold ...
