对泉山金矿氰化尾矿进行了焙烧预处理—超声波强化硫脲浸金试验研究.其结果表明:该尾矿经焙烧后硫脲浸出,金的最高浸出率比未焙烧时提高了45.12%;尾矿焙烧后再经超声波强化硫脲浸出,金的最高浸出率进一步提高了9.6%,达到77.5%,且大大缩短了浸出时间,提高了浸金效率.
@@@@Experimental study on cyanide tailings roasting-ultrasonic wave enhanced gold extraction using thiourea in Quanshan gold mine was conducted .The results showed that with tailings roasted and leached by thiourea ,the high-est gold leaching rate was increased by 45.12%compared to that before roasting.After roasting,the concentrates are leached by ultrasonic wave enhanced thiourea ,which made the leach rate further increased by 9.6 %, reaching 77.5 %and greatly reduced the leaching time improving the leaching efficiency .
