近几十年来有色金属生产的特点是增加了湿法冶金的比例。湿法冶金不仅补充了传统的火法冶金工艺,而且成功地同它们竞争。在许多情况下,湿法冶金是获得金属的唯一方法。它能够处理难选的复杂原料,扩大产品品种,建立自动化过程,这些都是湿法冶金工艺公认 In recent decades, non-ferrous metal production is characterized by an increase of the proportion of hydrometallurgy. Hydrometallurgy not only complements the traditional pyrometallurgical processes but also successfully competes with them. In many cases, hydrometallurgy is the only way to get the metal. It is capable of handling difficult and complex raw materials, expanding product varieties and establishing automation processes, all of which are recognized as hydrometallurgical processes
