摘要
环境污染和能源短缺是重有色金属冶炼的两大障碍。在对重有色金属湿法冶金存在主要问题进行分析的基础上研究成功的矿浆电解新技术，是一种清洁、高效的提取冶金。它具有流程短、能耗低、金属分离好和环境污染少等特点。矿浆电解的显著特点是充分利用了电积过程的阳极反应来浸出矿石，工艺能耗大大降低；在电解槽中硫化物转化为元素硫，而不产生硫酸，有利于环境保护。文章描述了国内外矿浆电解技术的发展过程及我国建立的世界上第一个矿浆电解工业生产厂的概况，指出我国在该领域处于世界领先地位和矿浆电解技术具有很好的前景。
Environmental pollution and energy shortage are two main barriers for the development of heavy non-ferrous metallurgical industry. Slurry electrolysis process, which is researched on the basis of analyzing the main problems in heavy non-ferrous hydrometallurgy, is a clean, energy efficiency extractive metallurgical method. It has many advantages, such as short process, low energy consumption, efficient metal separation, low environmental pollution, and so on. The notable character of SEP is that leaching ores can be completed through anode oxidation during electrowinning, which can greatly reduce energy consumption. In cells, the sulfur from sulfides will be converted to elemental sulfur rather than sulfuric acid, which is good for environmental protection. This paper describes the domestic and international development of slurry electrolysis process (SEP), and introduces the situation of the first commercial SEP plant in the world, which is designed by China. This paper also points out that China is in world leading in this field and SEP will have good prospect in the future.
