01-07-2010· The optimum parameters were 4000 mg/L for cyanide concentration, pH = 11.1 and 24-h cyanidation time for the first sample; and 2500 mg/L, pH = 10.5 and 24 h for the second sample. Silver and gold recoveries were 94.91% and 28.2% respectively for the first sample and 92.5% and 93.5% for the second sample.

Cyanidation of gold ores containing copper, silver, lead, arsenic and antimony
Cyanidation of gold ores containing copper, silver, lead, arsenic and antimony
Jul 01 2010 · Cyanidation of gold ores containing copper silver lead arsenic and antimony The first sample contained 105 ppm gold with high arsenic and antimony The second sample had a low gold content 25 ppm but a high silver content 160 ppm
204 204 Cyanidation of Refractory Gold Ores: A Review R.K. Asamoah, R. K. Amankwah and J. Addai-Mensah Ian Wark Research Institute, The ARC Special Research Centre for Particle and Material
The gold is mixed with the sodium cyanide which leads to the following Elseners equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.
In flotation of gold-containing 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 ·7H. 2. O, SO. 2,Na. 2. S.
cyanidation of gold ores containing antimony-ZXing Machinery ,Jul 01 2010Cyanidation of gold ores containing copper silver lead arsenic and antimony The chemical reactions that take place during the cyanidation of concentrate for ores can be very complex Luna and Lapidus 2000 Since a large proportion of gold ores contain sulfide minerals the effects of these minerals on gold dissolution in cyanide
The gold- and silver-bearing copper ores exhibit great differences in form and age; neither do all the occurrences yield much gold or silver, and, moreover, they are of more importance as gold producers, silver being less often associated with the copper. 3. Lead-bearing Silver ores: These are silver ores containing 4 percent or more of lead.

204 204 Cyanidation of Refractory Gold Ores: A Review R.K. Asamoah, R. K. Amankwah and J. Addai-Mensah Ian Wark Research Institute, The ARC Special Research Centre for Particle and Material
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
Jul 01 2010 · Cyanidation of gold ores containing copper silver lead arsenic and antimony The first sample contained 105 ppm gold with high arsenic and antimony The second sample had a low gold content 25 ppm but a high silver content 160 ppm
A hydrometallurgical process for treating copper feed materials containing gold and/or silver by simultaneously leaching copper, gold and/or silver into an aqueous cyanide solution, recovering copper in metallic form by electrowinning and regenerating cyanide ions is provided, wherein high current efficiencies are achieved at high current densities and at low copper concentrations.
16-09-1997· Hydrometallurgical extraction and recovery of copper, gold, and silver via cyanidation and electrowinning Gold ores containing high concentrations of cyanide-soluble copper minerals, e.g., chalcocite it utilizes low current density, requires high copper concentrations and leads to the oxidation of cyanide at the anode.
Many gold-silver ores, especially oxidized ores can be processed by cyanidation method. In the process of cyanidation , chlorargyrite dissolves fastest, but natural silver and the simple sulfides of silver that form natural alloys of natural silver and other

This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.
gold ores to crush antimony - detskylekar-zamarska.cz ,Gold Ore Contain Antimony - wwprojekt. ores containing antimony - Cyanidation of gold ores containing copper silver lead Abstract Cyanidation tests on two ore samples from two different gold deposits are reported The first sample contained 105 ppm gold with high arsenic and antimony.
The gold- and silver-bearing copper ores exhibit great differences in form and age; neither do all the occurrences yield much gold or silver, and, moreover, they are of more importance as gold producers, silver being less often associated with the copper. 3.
