Abstract:

To solve the problem of refractory ore types of one gold mine in Gansu Province，we propose a process method of cyanidation leaching from arsenic-carbon gold ore.The study shows that the ore pre-treatment using concentration of 15% NaOH and 2% H2O2 can effectively eliminate the affect of arsenic to cyanide leaching gold.At the same time，we can reduce carbon interference using the method of adding kerosene，it makes carbon activity in ore samples produce passivation，thereby eliminating“robbing gold role”of carbon.The process method can make gold cyanide leaching rate increased to 95%，it has a good economic and social benefits.

Key words: Arsenic-carbon gold ore, Cyanidation, Leaching rate, Leaching gold test, Gansu Province
