目前在世界上随着科学技术的发展,黄金的需要量不断地增加,由于过去大量的开采处理富矿,使地下的黄金资源逐步减少,矿石的含金品位越来越低,而金的嵌布粒度多呈细粒,采用一般的物理选矿法很难获得满意的效果.因此,必须扩大资源处理,研究最佳的提金工艺以满足黄金生产的需要.在扩大资源处理方面,除增大地下资源处理量外,还需从含金尾矿等废物料中回收金.在提金工艺方面,由于资源物料中的组 At present, with the development of science and technology in the world, the demand for gold continuously increases. Due to the massive exploitation of rich ore in the past, the underground gold resources are gradually reduced, the gold content of ore is getting lower and lower, Therefore, it is necessary to expand resource processing and study the best gold extraction process to meet the needs of gold production. In terms of expanding resource processing, in addition to increasing the underground Resource handling capacity, but also need to recover gold from waste materials such as gold tailings.In the gold extraction process, due to the resource material in the group
