摘要: In order to understand the oxidation degree of the refractory gold oxide slag in Sanhe gold industry,Jiangxi Province,the chemical composition,mineral composition,occurrence state of element and dissemination relationship of inter-mineral were studied by chemical analysis,XRD,laser particle size analysis,optical microscope and energy spectrum analysis.The results show that the intergrowth of gold mineral and pyrite in the oxidation slag is inclusion intergrowth,4.17% of the intergrowth of gold mineral and nonmetallic mineral are inclusions.The total gold content of inclusions is 4.85%,which is an important reason for affecting the leaching rate.
