金银铜多金属黄铁矿烧渣综合回收试验研究OA北大核心CSCDCSTPCD
Experimental study on comprehensive utilization of Au -Ag -Cu polymetallic pyrite cinders
根据黄铁矿烧渣的物理、化学性质特征,完成了多金属综合回收试验.结果表明:烧渣组成以氧化铁为主,并含有贵金属及有色金属,部分金、银、铜包裹于黄铁矿等硫化物中,而锌主要以铁酸锌形式存在.对烧渣进行氰化浸出,在试样未磨情况下,采用石灰调节矿浆pH =10 ～11、矿浆浓度35％、浸出时间24h、氰化钠耗量6kg·t-1的试验条件,可以获得金、银浸出率分别为67.25％、60.08％；采用浮选法处理烧渣可获得金品位8.66g· t-1、回收率为37.82…查看全部>>
Based on the physical and chemical characteristics of the pyrite cinders, experimental study on comprehensive recovery of pyrite cinders are carried out. The results of the tests indicate that pyrite cinders are mainly comprised of ferric oxide and abundant with gold, silver, copper and zinc. A part of gold, silver and copper is included in sulfide such as pyrite and zinc is mainly existed in zinc fer-rite. Under the condition of alkaline slurry which pH val…查看全部>>
