In the extraction aspect, the paper discloses two different extraction schemes on treating refractory ores, namely pretreatment followed by gold leaching and direct leaching. Pretreatment process involving roasting chemical oxidation and bio-oxidation have been discussed. Direct leaching of gold ore processing such as heap leaching, carbon in pulp (CIP), carbon in leach (CIL) and resin in pulp (RIP) are summarized. This paper also dicloses in a detailed manner the research approach on the development of alternative leach reagents which could improve environmental concerns as compared to the use of cyanide.

Thus, according to MineSpans data, 54 percent of gold production from refractory deposits comes from mines situated in the bottom half of the cost curve, while only 18 percent sits in the fourth quartile (Exhibit 5). This high-grade effect is expected to remain in place at least until 2023, but grade erosion should dampen it over time.


In order to generate the most value from refractory gold ore cip extraction plant and prevent longer-term distress due to grade erosion, we see three main areas for action that miners should consider:

The role of biotechnology in different facets of gold extraction metallurgy is illustrated with respect to biogenesis of gold ore processing plant, biobenefication, bioliberation and bioenvironmental control. The use and commerical potential of this technology are discussed with reference to the mining and processing of Hutti gold ores.A Review of the Cyanidation Treatment of Copper ore Separation and Concentrates
