Biotechnological Approaches to Facilitate Gold Recovery from Double

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 carbonaceous matter content, but …

Technology options for processing complex and double refractory gold ore

The initial results for the cyanide leach gold recoveries were very poor on a high-grade primary sulphide ore of 6.2 g/t Au with no silver. Subsequent mineralogy showed the ore to be a characteristic pyrite, carbonaceous refractory gold ore (double refractory). This was a very disappointing finding. A small scale gravity and flotation test programme was developed to …
