摘要
某银金矿矿石中有用金属甚多 ,相互关系密切 ,银主要以类质同像状态分散赋存在各种硫化矿物及铁矾类、氧化锰矿物中 ,用常规选矿方法难以选别 ,对该矿石的选别工艺流程作了研究 ,认为氧化焙烧—氯化焙烧—氰化工艺流程较适合该矿矿石性质 ,获得的指标最好。
There are many valuable metals existing in a type of silver-gold ore.The silver mainly distributed in the state of isomorphism in various sulfide minerals,pissophanite and manganese oxide minerals.It is very difficult to treat this kind of ore by using the conventional flotation method.Thus the mineral processing study on this kind of ore was conducted and good results were achieved by applying the separation process,i.e.,oxidation roasting-chlorination roasting-cyanidation,to treat this kind of ore.
