Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and goldcontaining stibnite concentrate ore (AsAuSb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about % and %, respectively.
Gold Extraction and ... available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen. For refractory ores such as
Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890''s, 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.
Apr 14, 2008· It is cheaper currently to use traditional smelting to extract copper from its ore, so bioleaching is not used in this case, but it is used more and more in gold extraction, since much of the ore has very little gold in it, so bioleaching is a cost effective option here (bioleaching is also used for refractory gold ore, that is, ore in which ...

Arsenic | Minerals Education Coalition. Arsenic (As) is classed as a semimetal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and ...
The cyanidation method consumes a lot of chemicals and oxygen, but it still cannot extract gold fully. 7. Gold arsenic sulfide gold ore. Gold arsenic sulfide gold ore refers to the gold ore associated with arsenic sulfide, mostly are pyrite and arsenic pyrite, because arsenic pyrite is the second gold pyritecontaining sulfide mineral in gold ore.
Jul 18, 2013· Abstract The processing of gold bearing sulphide minerals which contain arsenopyrite and other complex arsenic sulphide minerals results in arsenic containing emissions and effluents which must be given careful consideration in relation to clean air and clean water standards. The sources of arsenic and the various process options for treating arsenical gold ores and concentrates are briefly ...
This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don''t want to melt them.
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
