在全党全民办工业,以钢为纲带动一切工业的形势下,炼铜工作具有很大的重要性,全民炼铜已经被提到日程上来。但搞铜与搞钢铁有许多不同之处,搞铁的主要问题是要解决冶炼中的鼓风,而搞铜的关键则在于选矿。从下面的一些分析,我们便可以抓住当前铜生产的关键问题所在。一、从资源情况来看地壳中所含有的铜在生成矿脉时虽然情况各界,但是可以这样说,大部分矿床的平均含铜品位都在1％以下。虽然在整个矿脉中也有些品位较高的富矿,但其数量是很少的,一般来说,铜资源总量中约有90％以上
In the situation where the entire party runs its own industry and steel is the key link in moving all industries, the work of copper smelting is of great importance. Copper smelting by the whole people has been put on the agenda. However, there are many differences between engaging in copper and engaging in steelmaking. The main problem with ironmaking is to solve the problem of blasting in smelting. The key to engaging in copper production lies in ore dressing. From the following analysis, we can grasp the key issues of the current copper production. First, from the point of view of resources, the copper contained in the crust, although various in the formation of veins, can be said that the average copper content of most deposits are below 1%. Although there are some high-grade bonanza throughout the veins, the quantity is very small, and in general, about 90% of the total copper resources
