摘要
对刚果民主共和国某铜钴矿山废石样品的选矿试验研究表明,在样品含铜1.2%、含钴0.022%,铜氧化率为89.58%、钴氧化率为81.90%的情况下,原矿磨矿至-0.074 mm占75%,采用先硫后氧的异步浮选工艺,且粗精矿经过三次精选后,能得到硫化铜精矿、氧化铜精矿两个精矿产品,总铜回收率达78%,因此该工艺流程具有较高的实际应用价值。
It shows from research on mineral processing test of waste rock samples of a copper-cobalt mine in the Democratic Republic of Congo that the sample contains 1.2% of copper with oxidation rate of 89.58% and 0.022% of cobalt with oxidation rate of 81.90%,After grinding the ores to-0.074 mm accounting for 75%,it adopts the asynchronous flotation process of sulphurization firstly and then oxidation,and copper sulphide concentrate and copper oxide concentrate can be obtained from rough concentrate after being cleaned for three times,the total copper recovery reaches 78%,therefore,the process has relatively high practical application value.
