Double refractory gold ores, such as Barrick's Goldstrike ore, contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching.
The presence of carbonaceous matter and encapsulation of gold in sulfide minerals in double refractory ore results in poor efficiency of the gold recovery. According to the estimates, double refractory ore accounts for nearly a third of the global gold production that is now accessible, which indicates a developing market for the extraction …
Double refractory gold ore (DRGO) not only include ppt levels of gold grains locked in sulfide minerals but also a problematic amount of carbonaceous matter. This causes a significant recovery loss of gold during cyanidation because of the strong affinity of the Au(CN)2− with the carbonaceous matter. Combustion decreases the …
Gold miners are facing a reserves crisis, and what is left in the ground is becoming more and more challenging to process. Refractory gold reserves, which require more …

The presence of carbonaceous matter and encapsulation of gold in sulfide minerals in double refractory ore results in poor efficiency of the gold recovery. According to the …
Technologies focusing on the use of physical, chemical and biological methods have been developed to reduce the concentration of cyanide and cyanide compounds in wastewaters to permissible limits. This chapter reviews the current and emerging technologies for treatment of cyanide from wastewaters generated in gold …
Refractory gold ore is usually affected by the associated carbonaceous matter through the preg-robbing effect, which is eliminated by oxidation roasting, followed by leaching, to achieve a satisfactory gold leaching efficiency. Roasting–leaching experiments, pore structure measurements, scanning electron microscopy (SEM), and X-ray diffraction …
Given the lack of information about the environmental footprints of gold production, this study aims to fill this gap by providing a detailed LCA on gold extraction from double re- fractory ore in ...
