Extraction of gold from an Indian low-grade refractory

2003-2-1 1.. IntroductionWith the fast depletion of high-grade gold ores, the dependence on low-grade ores may increase globally in the near future. When a gold ore is below the cut-off level (1.75 g/t), it will not be economical to use such ore directly.

Extraction of gold from an Indian low-grade refractory

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 14 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.

Extraction of gold from an Indian low-grade refractory

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. Thiourea leaching of this flotation concentrate after pressure, pre-oxidation has resulted in gold extraction of 98%, with an overall gold recovery of 74%.
