In the present study, the effect of zinc cyanide on the flotation of gold from a pyritic ore was evaluated and the competitive adsorption between zinc cyanide species and the collector, potassium amyl xanthate (PAX) or Aerophine promoter (3418A), on gold was studied .
A process for treating a particulated gold bearing ore to recover the gold therein is disclosed. The process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination of the ore at a temperature of about 350° C. in the presence of iron to form a mixture of volatile gold chlorides and volatile goldiron chlorides in the chlorine off gases followed by condensing ...

Gold extraction Wikipedia. Gold extraction refers to the processes required to extract gold from its ores. This may require a Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.
It is not uncommon for prospectors, especially those who operate metal detectors, to find a rich gold bearing specimens of ore. Sometimes the best use of these minerals is to sell them at specimens. There are collectors who will pay top dollar for beautiful mineral specimens that contain significant gold.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
Other Free Milling Ores Gold mineralization in these ores may occur in a limey siltstone containing intermittent shale beds. Sulfides are seldom seen, but pyrite, galena, sphalerite, chalcopyrite, antimony, mercury and arsenic occur in minute amounts. Gold occurring in micron size is readily amenable to cyanidation as at Carlin and Cortez.

GoldPyrite ores. Gold has varying modes of occurrence in sulphide ores ranging from being disseminated and interstitial in minerals such as lead and copper, in oxide ores particularly as disseminated particles, and as free milling gold or association with tellurides. Where the gold is intimately associated with various sulphide minerals ...
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 complex. It is the most commonly used leaching process for gold extraction.

Generally there are two types of gold: primary gold ("mountain gold" from mines) and secondary gold ("stream gold", "nuggets"). Above all the extraction of primary gold is associated with considerable effort. There are various methods to free the gold particles from their solid mantle in the ore extracted .
The goldcontaining refractory sulfide ores of chalcopyrite, pyrite, baritepolymetallic, quartzites, copperzinc, antimonite were used in the research. As a result of investigation, the optimal conditions of gold leaching by means of thiourea method from the abovementioned ores and concentrates with 8590% gold extraction were established.
