Silver and gold recoveries were % and % Gold ores respectively for the rst sample and % and % for the second sample. Cyanidation In the second series of test work, H2O2 ( M), air ( L/min) and a mixture of H2O2 and air were used Reaction kinetics as oxidizing agents to improve the gold extraction kinetics of the rst sample.

#0183;#32;Gold cyanidation 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. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of
The invention relates to the metallurgy of nonferrous metals, mainly to metallurgy of copper, silver and gold, and in particular to methods of extracting metals from goldbearing sulfide is oxidized copper ores in which the gold is associated with sulphides of copper and other mineral products.
In this study, cyanidation experiments were carried out on a massive sulfide ore sample, whose grades of the precious metals gold and silver were found to be g/t and g/t, respectively. Other elements in the ore were arsenic with average grade of 1,/t; antimony, g/t; zinc, g/t; copper, g/t; lead, g/t; mercury, g/t; and bismuth, g/t. The first
The optimum parameters were 4000 mg/L for cyanide concentration, pH = and 24h cyanidation time for the first sample; and 2500 mg/L, pH = and 24 h for the second sample. Silver and gold recoveries were % and % respectively for the first sample and % and % for the second sample.

In flotation of goldcontaining base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 #183;7H. 2. O, SO. 2,Na. 2. S.
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 is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
Cyanidation of gold ores containing copper, silver, lead, arsenic and antimony. The first sample contained ppm gold with high arsenic and antimony. The second sample had a low gold content ( ppm) but a high silver content (160 ppm). gold cyanidation crusher
The gold mud is smelted into the ingot to obtain the gold and silver alloy, and the gold removal solution (containing gold g/ton) is detoxified with bleaching powder or chlorine gas. The washed filter cake, cyanide tailings, is sent to the molybdenum flotation operation (adding No. 2
