某贫硫化物复杂含金矿石选冶技术研究与应用

A process of recovering gold from the finely disseminated gold ore with minor sulphides and its application

吉林省临江市金银矿对现场生产工艺流程进行了改造。采用浮选—浮尾氰化炭浸工艺流程取代了原全泥氰化炭浸生产工艺流程,金的回收率由改造前的5 0 .96 %提高到82 .5 4% ,同时在不增加设备和投资的前提下,选厂处理能力由原来的10 0t/d左右提高到180t/d ,生产成本由原来的2 2 2 .76元/t,降低到177.31元/t ,每年可为企业增加效益115 7.4 0万元。

The reformations of operating processes were conducted. Flotation and tailing to cyanidation replaced the formal all-slime cyanidation and CIL,Raising gold recovery from 50.91% to 82.54% and milling capacity from 100t/d to 180t/d without adding equipments and investment. Operating cost is decreased from 227.6RMB/t to 177.31RMB/t,increasing in benefit by 1157.40×10 4 RMB each year.
