Recovery Problems in Gold Ore Processing with Emphasis on

The present paper briefly describes the methods of gold ore processing and the associated problems are grouped into mineralogical, chemical and physical. The processing of low grade gold ores by heap leaching is an important technological development. But a major drawback in heap leaching process is low recovery of the precious metals.

Gold processing Britannica

With ores of higher gold content (i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.

The leaching and adsorption behaviour of gold ores

Diagnostic leaching was used to show that mineralogy was not an important factor in the enhanced gold extraction in the presence of activated carbon for the ores. Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg-robbing at the ore surface.
