Based on the property of a carbonaceous arsenious gold ore from Laos,the paper has explored the process of CIP leaching,run-of-mill ore roasting-roasting slag leaching,flotation-flotation concentrate roasting-roasting slag leaching,flotation carbon concentrate decarbonizing roasting-bio-oxidation-leaching.The results show that compared to the other 3 processes,the flotation-flotation concentrate roasting-roasting slag leaching joint process is more suitable for the ore.Under test conditions,the gold recovery rate of flotation concentrates is 95.16 %,the gold leaching rate of roasting slag leaching is 88.60 %,the gold total recovery rate of overall flowsheet is 84.31 %.
