Refractory gold ores in Archaean greenstones, Western

Pyritic ores are free-milling to mildly refractory, or rarely moderately refractory. Pyrite in pyritic ores contains negligible to low levels of submicroscopic gold (<5 ppm). Other reasons for refractory behaviour in pyritic ores include very fine-grained native gold inclusions in pyrite, or the presence of gold-bearing tellurides.

Recovery of gold from refractory auriferous iron

A process for recovering gold from refractory auriferous iron containing sulphidic material which comprises treating an aqueous slurry of the material in a pressure oxidation step at a temperature in the range of from about 135° to about 250° C. under a total pressure of from about 500 to about 5000 kPa to oxidize sulphide sulphur to sulphate form and release gold from a refractory state.

How to Improve the Refractory Gold Leaching Process?

18-08-2020· Refractory gold ore refers to the part of gold ore that cannot be extracted effectively by the conventional cyanide leaching process after the fine grinding. The gold in this type of gold ore cannot contact with the cyanide solution due to physical encapsulation or chemical combination, resulting in a very low gold leaching rate.

What are Refractory Metals

What are refractory metals? Refractory metals have one characteristic in common: an exceptionally high melting point. Tungsten, for example, melts at 3410oC (6170oF), which is more than double that of iron and ten times that of lead. As a group, they are found in one section of the periodic table of elements.
