Gold extraction A "refractory"gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.

    The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silvertelluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].

    REFRACTORY ORE PROCESSING. The common definition of refractory gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.

    Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

    The mineralogy determines the recovery process of gold. Two types of gold ores can be distinguished: Non refractoryores and refractory ores. Non refractory gold ores permit a straightforward recovery by a relatively simple conventional technology. Refractory gold ores, however, require rather sophisticated recovery techniques.

    1. Gold ores and their metallurgical treatment Only a few minerals are important as gold carriers. Native gold is by far the most important, followed by gold tellurides. Other gold compounds are economically irrelevant. There is a series of minerals that can carry gold as a physical constituent such as pyrite and arsenopyrite.
