摘要
Abstract
Recovery of valuable metals from refractory high-grade copper-contained gold concentrate was researched by the process of sulfating roasting-acid leaching-cyanidation leaching .The optimum conditions are that 1)Roasting temperature is 650 ℃ ,roasting time is 2 hours .2)Leaching of copper is over 98 .5% under the conditions of initial sulfuric acid concentration of 50 g/L ,leaching temperature of 80 ℃ ,leaching time of 2h ,liquid-solid ratio of 4∶1 -5∶1 ,the copper mass fraction in the acid leaching residue is lower 0 .35% .3)The cyanidation leaching of gold and silver are 96 .5% and 63 .5% , respectively .The process can be used for extracting valuable metals from refractory high-grade copper-contained gold concentrate .关键词
