The characteristics of refractory gold ores and the principles of selecting pretreatment program are introduced.The development and new trends of the methods of roast,pressure oxidation and bio .

Developments in the pretreatment of refractory gold ...Such ores require a pre-treatment process to alter or destroy the sulphide matrix and render the gold accessible to cyanide and oxygen (Gudyanga et al., 1999). The gold in high-sulphur and high- arsenic refractory gold concentrate (HGC) is encapsulated as fine grained particles in the crystal structure of the mineral matrix, which renders the metal inaccessible to the leaching agent (Abrantes ...

Microbial Pretreatment of Refractory Gold Ore .

Gold ore which is difficult to concentrate often referred to gold or refractory gold ore, which use conventional cyanide process cannot effectively extract most of the gold ore. Therefore, it is commonly said that the treatment of gold is the case of the cyanide method. Part of refractory gold ores of gold particles with fine gold or submicroscopic gold a parcel or disseminated exist in ...Processing Techniques for Difficult-to-treat Ores .(1989). Processing Techniques for Difficult-to-treat Ores by Combining Chemical Metallurgy and Mineral Processing. Mineral Processing and Extractive Metallurgy Review: Vol. 4, No. 3-4, pp. .sulphide ore refractory - .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 pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic ...The mechanism of leaching of gold from .ABSTRACT Refractory gold ores commonly contain free gold, suhmicroscopic gold. base metal sulphides, pyrite, pyrrhotite, labile sulphides and carhonaceous material. The analysis of gold deportment with the diagnostic leaching technique has opened a research field to gain more insight into the fundamentals of the kinetic behaviour of gold dissolution from refractory ores. Hence, more detailed ...
