Refractory Gold Technology

Refractory Gold Technology

Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite andor arsenopyrite, unavailable for recovery by conventional leaching. In Sherritts gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold.

Gold Tailings Reprocessing Technology

Gold Tailings Reprocessing Technology

In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity and low-grade gold tailings is common heap leaching.

Desulfurization of the Old Tailings at the AuAgCu

Desulfurization of the Old Tailings at the AuAgCu

sulde minerals, including pyrite, sphalerite, arsenopyrite, chalcopyrite, galena. The otation results conrmed that environmental desulfurization is e ective at reducing the overall sulde content in the tailings. The recovery of suldes was between 69 and 75, while Au recovery weight-yield was between 2.8 and 4.7.
