在金属生产中运用氯化提取技术始于铜分族元素—Cu、Ag、Au,这至少已有两百多年的历史。而其最成功的运用,迄今是在稀有金属部门。随着环境污染、能源危机、资源贫化这些重大深远问题的出现,整个冶金工业面临着发展新的提取技术的挑战。在这种形势下,氯化提取受到了愈来愈多的重视,在遍及轻重稀贵整个有色冶金领 The use of chloride extraction technology in metal production began with the copper-Cu, Ag, Au, which has been at least two hundred years old. And its most successful use so far is in the rare metals sector. With the emergence of such major and far-reaching problems as environmental pollution, energy crisis and resource depletion, the entire metallurgical industry is faced with the challenge of developing new extraction technologies. In this situation, the extraction of chlorinated by more and more attention, throughout the rare and precious throughout the non-ferrous metallurgical collar
