Arsenic and Antimony Sulphide Minerals in Cyanidation

Sep 17, 2014 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.

The Treatment of Antimonial Gold Ores

(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.

Basic theory and optimization of gold 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

ELECTROCHEMICAL GOLD EXTRACTION FROM THE RESIDUES

Most of gold-containing antimony ores are resistant to the common process of gold extraction-treatment with cyanide. One of the reasons of this resistance is a presence of finely-impregnated gold in sulfide mineral of arsenic and antimony. Further, antimonite sulfide destroys cyanide.

17 Flotation of Gold Ores

17.5 FLOTATION OF GOLD-CONTAINING MERCURY/ANTIMONY ORES In general, these ores belong to a group of difficult-to-treat ores, where cyanidation usually produces poor extraction. Mercury is partially soluble in cyanide, which increases consumption and reduces extraction. A successful flotation method [5] has

Cyanide Leaching Chemistry & Gold Cyanidation

Feb 06, 2015 Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu (CN)2 + 4 NaOH. Cyanide Leaching Chemistry. In a relatively simple system of this type the gold dissolves readily. The only requirements are that the gold be free and clean, that the cyanide solution contain no
