提高利用矿石原料的完备性是矿山和冶金工业在第十个五年计划中的迫切任务之一。同时有色金属工业矿石总量的5—20%在采掘时被丢掉,相当大量的金属被矿水带走。从这样的原料中提取铜所需的投资比从新矿区的矿石中制取铜大约低2倍。从非工业矿石和废渣中提取铜最合理的方法是国外已获得广泛发展的地下浸出和堆浸。从得到的含有大
One of the urgent tasks of the mining and metallurgical industry in the 10th Five Year Plan is to improve the completeness of the utilization of raw materials for ore. At the same time, 5-20% of the total non-ferrous metal industrial ore is lost during excavation, and a considerable amount of metal is taken away by the mineral water. The investment required to extract copper from such raw materials is about two times lower than that from copper from the new mines. The most reasonable method for extracting copper from non-industrial ores and waste is the widespread underground leaching and heap leaching that has been obtained abroad. Contained from the big
