为了使同志们对我们所生产的有色金属矿物认识更加明确,我们将在本栏内,对各种有关的有色金属矿物逐一加以介绍。现在首先发表了面这篇「铋」的文章。铋是一种产量较少,而价值昂贵的有色金属,在充分利用有价金属资源的原则下,我们在一九五二年内将进行金属铋的回收。这篇文章简要而系统地介绍了铋的性质、用途和冶炼方法,是可以供做同志们工作上的参考的。 In order to make our comrades know more about the non-ferrous metal minerals we produce, we will introduce each related non-ferrous metal mineral in this column one by one. Now the first to publish this “bismuth” article. Bismuth is a non-ferrous metal that is less valuable and more expensive. Under the principle of making full use of valuable metal resources, bismuth will be recovered in 1952. This article gives a brief but systematic introduction of the properties, uses and smelting methods of bismuth, which can serve as a reference for comrades working.
