Abstract

This paper described the process mineralogy and beneficiation tests research on a magmatic rocks native gold mine of the grade is 4.92×10-6.The native gold is magmatic rocks type gold mine mineralized with arsenopyrite and pyrite,metal minerals are mainly pyrite and arsenopyrite,gangue minerals are mainly altered minerals,such as white mica and amphibole.It is difficult to leach with conventional carbon leaching and all slime cyanide leaching.Under the grinding fineness is 58.2% below 0.074 mm,by once roughing,once cleaning,once scavenging,cleaning tailings and scavenging concentrates combine return roughing,closed-circuit flotation experiment is carried out,gold concentrates containing 56.6×10-6 Au with recovery of 96.43%,gold tailings is only 0.19×10-6 are obtained.The flotation gold concentrate are high arsenic and sulfur.
