Abstract:

High sulfur gold concentrate in the pressure oxidation process will produce a large amount of basic iron sulfate.It cause a huge amount of lime in cyanidation,then the slurry viscosity increased rapidly,liquidity deterioration,and make the process worse.The flotation process for a refractory gold ore from northwest China is optimized to lower the sulfur grade of flotation concentrate which treated by POX,the gold recovery of flotation has been improved,and the lime dosage in cyanidation reduced to the normal range,the gold leaching rate is more than 98%.The flotation-POX combined technology provides a good solution for gold concentrate in the pressure oxidation process.

Key words: gold concentrate, pressure oxidation, basic iron sulfate, Flotation-POX combined technology
