CIL mainly applies for the process of above 1g/t grade gold ore and gold ore with large bearing ore volume: silver, platinum, copper, etc. As CIL sees a better performance in extracting these minerals at the same time. And Xinhai Mineral Dressing Test Center can help you with the
#0183;#32;Unlike gold cyanide, which is very stable and does not decompose easily in most applications, stability of the gold halide complex is dependent on the solution pH value, composition (with respect to halide concentration), solution potential and the presence of reductants (such as metals and sulfidic minerals) in the ores.
CNFREE Ecofriendly gold leaching chemical is socalled nontoxic and cyanidefree gold dressing agent, which can replace sodium cyanide without changing the original equipment and cyanide process.
Gold content is very low in ore. To extract gold, need crush and grind ore and use mineral processing technology to pre concentrate or separate gold. For gold dressing, the gravity separation, flotation and cyaniding are widely used. The CIL are widely used in Africa. Gold CIL process. Gold flotation process.
Ore Dressing Sodium Cyanide In Gold Ore Dressing As a leading global manufacturer of crushing equipment milling equipmentdressing equipmentdrying equipment and briquette equipment etc we offer advanced rational solutions for any sizereduction requirements including quarry aggregate grinding production and complete plant plan.
According to the ore properties, grade, through the tests determine the optimal dosage and whether needs additives, generally kg of GDA per gram of gold or per ton of ore.

Ore Dressing Copper And Gold Extraction Process. Gold cil processyantai jinpeng mining machinery, ore carbon adsorption process is the most widely used in gold cyanide extraction principle in brief is the carbon could adsorb liquid gold from cyanide 1970s, withcyanidation carbon adsorption process is the most widely used in gold cyanide extraction process.
During the cyanidation process of ore, the surface of gold particles is in contact with the cyanide ore slurry, and the surface of gold particles may form sulfide film, peroxide film (such as calcium peroxide film), oxide film, insoluble cyanide film, etc. Surface passivation significantly reduces the oxidation and leaching speed of the gold particle surface.
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 cyanide
5. Gold loaded carbon desorption. 99% gold can be desorbed in only 26 hours with Xinhai hightemperature highpressure desorption method(150, ); The pregnant solution has higher concentrations of gold and silver cyanide complex ions and less impurity ions.
The cyanidation plants has been using sodium cyanide to dissolve the gold from the ore in order to recover the gold from the leaching solution. The formula is as follows: 2Au+4NaCN+O2+2H2O2Na[Au(CN)2]+2NaOH+H2O2. 2Au+4NaCN+H2O22Na[Au(CN)2]+2NaOH. From the electrochemical reaction, it can be known that dissolving 1 gram of gold consumes

During the cyanidation process of ore, the surface of gold particles is in contact with the cyanide ore slurry, and the surface of gold particles may form sulfide film, peroxide film (such as calcium peroxide film), oxide film, insoluble cyanide film, etc. Surface passivation significantly reduces the oxidation and leaching speed of the gold particle surface.
Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed the gold is liberated.
