前言近年来,真空冶金在多样化和专门化方面取得了很大进展,其应用扩展到各个领域,使某些本来无法实现的工艺成为可能。目前,我国真空冶金技术较为落后,在多金属矿物的分离提取方面尚无应用先例。矿物资源面临金属品位下降和成份复杂程度提高的趋势,致常规选冶法难于获得满意的技术经济
Introduction In recent years, vacuum metallurgy has made great progress in diversification and specialization. Its application has expanded to various fields, making certain processes that could not have been possible. At present, China’s vacuum metallurgy technology is relatively backward, there is no precedent for application in the separation and extraction of polymetallic minerals. Mineral resources are facing the decline of metal grade and composition of the trend of increasing the complexity of the conventional election Metallurgical Law difficult to obtain a satisfactory technical and economic
