Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
For Ilmenite beneficiation, a combined beneficiation method is often better than a single beneficiation method, which can better improve the ore grade and recovery rate. At present, the combined separation method for ilmenite can be divided into four kind
For Gold and Silver the most common leachants used are Na or K cyanides in the presence of oxygen Thiourea NH 2 2 also in the presence of oxygen or Ammonium polysulphide NH 4 2 Sx especially for Gold Optimum physical conditions for cyanidation are Maximum temperature of
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
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows 4 Au 8 NaCN O2 2 H20 4 NaAuCN2 4 NaOH

May 20 2013 · The most common method is cyanide leaching where cyanide salts in solution are used to suck the gold out from its ore You get gold but you
The use of neural network analysis of diagnostic leaching data both unmilled and milled ore characteristics The arrangement and shapes of these clusters could then be used to develop simple neural net models which were capable of predicting the degree of gold liberation ie gold leaching results more accurately than other presently used models
Leaching Gold With Cyanide Since the 1890s cyanide has been used to recover gold from gold bearing ores And today over 115 years later most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal Chemically it is a rather simple reaction
Oct 20 2014 · Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates Despite the difficulties and hazards of working with cyanide no other process has yet been proven to be an economic viable alternative
