A refractory gold ore from the Zancudo mine in Colombia were employed. The ASTM−100+ 200 mesh fractions (74–149 μm) of a mineral concentrate. from the Zancudo mine in Antioquia. The sample was classified by a standard method for sieve analysis, obtaining 1 kg in the particle size range between ASTM −100 + 200 mesh (75 to 150 μm).

AEROPHINE Ⓡ promoters are the flotation reagents of choice when treating Cu/Zn, Cu/Pb/Zn and especially Cu/Au/Ag/Pb/Zn ores. These ore types frequently have very high levels of pyrite and other iron sulphides. AEROPHINE Ⓡ promoters are highly recommended over xanthates when selectivity against iron sulphides (pyrite, pyrrhotite and arsenopyrite) is required.

Alternative lixiviants include bromides (acid and alkaline), chlorides and thiosulfate. The lower sensitivity to base metals (As, Pb, Cu, Sb, Zn) or impurities render possible the use of this process on many refractory gold ores. Thiourea leaching has been tried on different materials and ores with success.

They said it had a lot of silver and copper, but no gold. A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold.

Refractory gold ores have poor gold recoveries with direct cyanide leaching. Typically the refractoriness is due to encapsulation of the gold particles inside the host mineral. To liberate gold for leaching the host mineral must be broken by mechanical or chemical means.

10.12.2013· The present paper attempts to assess the effects of microwave irradiation on the leachability of refractory gold ores. Characteristics of the crystal structure and microstructure of the ores were determined by x-ray structural analysis (XRD) and scanning electron microscopy (SEM) before and after microwave irradiation. Compared to conventional processes, microwave leaching processes
