Abstract: Valuable elements of arsenic contain high sulfur and low grade gold ore from Anhui is gold and sulfur. In order to rationally develop and utilize the mineral resources, beneficiation test using sulfur suppression gold floating process was conducted. Using lime as sulfide inhibitor, butyl xanthate and butyl ammonium aerofloat combination reagent as collector, on grinding fineness of -0.074 mm 75%, by one roughing-three cleaning-two scavenging process, gold concentrate with 25.32 g/t Au, gold recovery of 68.52% satisfaction index was eventually obtained.

Key words: High sulphur gold ore, Flotation, Inhibitor
