我国有许多有色金属矿床含砷,其含量从万分之几到百分之几。随有色金属精矿带入冶炼厂的砷愈来愈多。由于砷的毒性给冶炼工艺和环境保护带来了许多困难和危害。近年来国内各有关单位对砷的防治虽进行了很多研究,取得了很大的成绩。但砷害的严重性仍未得到根本的解决。为了寻找根除砷害的新途径。本文着重介绍国内外有关含砷物料的真空热处理法。由于真空技术的迅速发展,真空冶金在我国重金属冶金中已开始了应用并取得了较好的经济效益与社会效益。真空冶金的主要优点之一就是环境保护好,基本
There are many non-ferrous metal deposits in China containing arsenic, its content from a few percent to a few percent. As a non-ferrous metal concentrate into the smelter more and more arsenic. As arsenic toxicity to the smelting process and environmental protection has brought many difficulties and hazards. In recent years, various domestic units have conducted a great deal of research on the prevention and control of arsenic and achieved great success. However, the seriousness of arsenic has not yet been fundamentally resolved. In order to find a new way to eradicate arsenic. This article focuses on the vacuum heat treatment of arsenic-bearing materials at home and abroad. Due to the rapid development of vacuum technology, vacuum metallurgy has begun to be applied in China’s heavy metal metallurgy and has achieved good economic and social benefits. One of the main advantages of vacuum metallurgy is environmental protection, basic
