41 in primary metallurgical processes for gold bearing ores gold is extracted with an alkaline cyanide solution metallurgical accounting process control and ore evaluation procedures depend on accurate precise and prompt measurements of the gold concentrations.

Amenability of an ore to the cyanidation process are gold leach efficiency and cyanide consumption as a function of the fineness of grind and other leach conditions refractory gold ore processes refractoriness results in poor gold recovery by standard processing techniques and can be due to either chemical or physical interference an.

this was the first commercial method used for gold extraction place the ore into the mortar and grind it to the size of sand grains put the ore grains into a plastic bowl add the 35percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker in a twotoone ratio of acid to bleach ensure that the liquid mixture is at.

cyanidation has established itself as the main process for extracting gold from ores in this century however many ores exhibit refractoriness to the conventional cyanidation process the main cause of the refractoriness is generally the presence of carbon tellurium and sulfides particularly those of antimony arsenic and iron.

Compared to the verde ores cyanide consumption and cost in the future processing of pancho ores at maricunga is expected to more than double with an associated sharp rise in copper levels in heap leach preg solutions allowing copper to continue to build in the heap leach solutions is seen as not an option.
