近些年来，湿法冶金在有色金属、贵金属和稀有金属领域中取得了突出的成绩，特别是在重有色、稀贵金属方面，各种堆浸技术、生物浸出技术发展尤为迅速。实践表明，湿法冶金技术是一种投资省、成本低、能耗少、污染轻的极具发展潜力的工艺技术，它可以处理其他工艺难以处理的低
In recent years, hydrometallurgy has made remarkable achievements in the fields of non-ferrous metals, precious metals and rare metals. Especially in heavy colored and rare precious metals, heap leaching and bioleaching technologies have developed rapidly. Practice shows that hydrometallurgy technology is a promising technology with low investment, low cost, less energy consumption and less pollution. It can handle the low-cost
