The refractory gold ore from Boka,Yunnan province,consists of small particles an dits carbon content is high.Based on the process mineralogy research of the refractory goldore,the various treating schemes for this gold ore,which were recom mended by design institutes,were analyzed and compared,it was pointed out that the mineral processing flowsheet of the oxidized ore should be all-slime cyanidat ion and carbon leaching,moreover,the mineral processing flowsheet of the primar y ore should be gravity separation-flotation,so the influence of high carbon con tent in the gold ore on the recovery rate of gold can be reduced,simultaneously production ideal indexes can be obtained,the recovery rate of gold ore can reaches as high as about 90%.
