Evaluation of leaching parameters for a refractory gold ore …

Abstract A cyanidation study was conducted on a mild refractory gold ore sample from the Central zone of Clarence Stream Property, owned by Freewest Resources Canada, to develop a leaching strategy to extract gold. Gold, at a grade of 8.00 g/t, is present as native gold, electrum and aurostibite. The ore also contains 2.8% pyrrhotite, together with several antimony minerals (0.8% berthierite ...Gold ore contain antimonyyanidation of gold ores containing copper, silver sciencedirect cyanidation tests on two ore samples from two different gold deposits are reported antimony mobilization through two contrasting gold ore ore and host rock contain abundant

Arsenic and Antimony Sulphide Minerals in Cyanidation

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 …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 ...

(PDF) Cyanidation of gold ores containing copper, silver, …

Cyanidation of gold ores containing copper, silver, lead, arsenic and antimony Fathi Habashi Introduction GeneralEarly studies on the dissolution of gold in cyanide solution in the presence of sulfide minerals have shown that heavy metal components, such as Cu, Fe and Zn, significantly increase the consumption of both cyanide and oxygen (Habashi, 1967;Dai and Jeffrey, 2006).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. ...

Gold Extraction from Different Types of Ore

Telluride gold ores generally refer to ores containing natural gold and sulfide minerals, which have high economic value. Gold extraction from this type of ore can be different, because whether this ore contains silver or not, it dissolves very slowly in cyanide solutions, so a pre-oxidation stage is usually added before cyanidation.(a) Ores in which a satisfactory gold extraction may be obtained by straight cyanidation, but which contain sufficient antimony to justify the production of an antimonial concentrate. CLASS 2. (b) Ores from which the gold extraction by straight cyanidation is unsatisfactory.
