Abstract:

The gold ore of Zhenyuan contains 0.75% (mass fract ion) arsenic, 1.53% antimony and 4.08% carbon., and gold is hardly cyanide leached mainly since parceled up by sulphuret. The gold cyanide leaching rate is 77.67% by roasting, but with in 82.31% with addition of auxiliary agent,then reaches as high as 87.63% ~93.22% with addition of 2 kg/t enhanced leaching agent.

Key words: gold concentrate, roasting, auxiliary agent
