目前各地中小型炼铜厂已突破技术关,投入正常生产。但是由于大多数工厂都是处理硫化矿,因此,不能一次炼成粗铜,而是先得到半成品——冰铜。有些地区炼出的冰铜品位较低,含杂質多,甚至还掺杂有大量的铜铁合金。如何处理这些半成品,使之成为国家所急需的金属铜,是当前各地铜厂迫切需要解决的问题。本文所介绍的一个方法,是简易可行的,在经济效果上也较令人满意,可供各地参考。 At present, small and medium-sized copper smelters have broken through technical barriers and put into normal production. However, since most of the plants are dealing with sulphide ores, it is not possible to produce blister copper in one go, but instead to obtain a semi-finished product, matte. In some areas, the matte grade is lower, contains more impurities, and even contains a large amount of copper-iron alloy. How to deal with these semi-finished products so that they become the state’s much-needed copper metal is an urgent need to be resolved by the copper mills all over the world. One of the methods presented in this article is simple and feasible and economically satisfactory, making it a good place for reference.
