卡扎兰矿床露天矿的大量废石是一种贫硫化矿和氧化矿岩石和无矿的二长岩的混合物,含有相当数量的铜和钼。本文介绍了亚美尼亚有色金属设计院1977—1980年间开展的细菌化学浸出法处理这类废石的可行性研究结果。第一阶段用四种粒级(-10+7,-7+5,-5+3和-3+1毫米)的老的和新的废石进行研究(表1),在2立升的玻璃漏斗中浸出,加料1.6公斤,浸出前润湿矿石,再
The large amount of waste rock in the open pit of the Cazandran deposit is a mixture of lean sulphide ore and oxide ore and non-ore-bearing monzonite, containing significant amounts of copper and molybdenum. This article presents the results of a feasibility study on bacterial chemical leaching of this type of waste rock carried out by the Armenian Nonferrous Metal Design Institute from 1977 to 1980. The first stage was studied with old and new waste rocks of four fractions (-10 + 7, -7 + 5, -5 + 3 and -3 + 1 mm) (Table 1) Leaching glass funnel, feeding 1.6 kg, wetting ore before leaching, and then
