Extraction of gold from an Indian low-grade refractory gold A low-grade gold ore from the southern region of India has been used in this study. Although cyanide has been the primary lixiviant for the extraction of gold for over a century now it is associated with certain shortcomings such as toxicity long leaching times and considerable interaction with other nonferrous metals present in the gold ores.

Extraction of gold from an Indian low-grade refractory gold 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%.
