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 carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach s
For beneficiation of gold ore, Tenova Mining Minerals liaises with suppliers and evaluates equipment to make unbiased selections of the best equipment for the job. and within the processing plant.
With the development of beneficiation technology, the definition of refractory gold ore is changing. Generally speaking, refractory gold ore in leaching field is a kind of ore whose leaching rate of gold is less than 80 when directly processed by cyanidation after find grinding
The work carried out on the processing of a low grade and refractory gold ore using thiourea is presented. Direct leaching of the as received ore with thiourea has yielded only 16 gold extraction. Starting with ore containing 1.4 g/t of gold, it has been possible to generate a sulphide concentrate with 6.1 g/t of gold by physical beneficiation of the ore through froth flotation
