今年三月份上级党委提出“以钢为钢”大搞优质高产的指示后,经过刻苦钻研,采用多种试验办法终于试验成功,大大提高了铜的回收率,由原来的火冶30～40%提高到水冶的80～90%,彻夜消除了杂质过多,铜铁不分的缺陷。从根本上改变了低品位氧化矿的冶金困难。现将我们的操作过程简单介绍如下。(一)使用工具:大缸若干个(溶浸用),竹筛(淘矿或过滤用),盆子(起液体倒缸用)木混(搅拌缸用)。以上工具仅作土法试验,或小型冶金之用,如资源丰富可根据湿法冶金原理,改进工具,增加设
In March this year, the superior party committee put forward the guideline of “making steel as steel” to engage in high-quality and high-yielding work. After making painstaking studies and finally adopting various test methods, it succeeded in testing and greatly enhanced the recovery rate of copper from 30% to 40% Increased to 80 ~ 90% of the water metallurgy, eliminate excessive impurities overnight, copper and iron regardless of defects. Metals fundamentally changed the metallurgical difficulties of low-grade oxide ore. Now our operation process is as follows. (A) the use of tools: a number of cylinder (dipping), bamboo sieve (Amoy mine or filter), basin (from the liquid inverted cylinder) wood mixed (mixing tank). The above tools are only for indigenous test, or for small metallurgy, such as resource-rich according to the hydrometallurgical principle, to improve tools, increase the set
