Cyanidation Of Gold Ore Containing Antimony
Gold containing antimony ore is a type of refractory gold in which gold is intimately associated with stibnite guo et al., 2017.When the traditional cyanidation method is used for gold extraction, thioantimonate by stibnite decomposition reacts with oxygen to form antimony acid salt, or antimony.
Cyanidation of gold ores containing copper, …
Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5 ppm gold with high arsenic and antimony. The second sample had a low gold content (2.5 ppm) but a high silver content (160 ppm). The first series of test work focused on the determination of conditions for extracting gold from the samples ground to − 75 μm. The optimum parameters were …

Arsenic and Antimony Sulphide Minerals in …
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become ‘foul.’ The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected. However, some arsenic and antimony …

gold extraction procedure from antimony ore
Gold extraction Wikipedia Gold extraction refers to These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold. Get Price Process flow-sheet for gold and antimony recovery . Main parameters studied were Na 2 S concentration, NaOH concentration, pulp density and temperature. After leaching, antimony has been recovered by electrodeposition, in ...
Gold cyanidation - Wikipedia
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.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents ...

Cyanide Leaching Chemistry & Gold Cyanidation
Products obtained from gold ores by flotation contain, in addition to gold and sulphide minerals, a large proportion of the reagents used for the flotation process. Such reagents are xanthates, dithiophosphates, frothing oils, copper sulphate and others. Reagents such as xan- thate which have rendered the gold floatable by making it water repellent have a similar effect in cyanidation. That is, they prevent to some extent contact between the gold …
