本世纪七十年代以来,随着湿法冶金工业的发展,为实现过程的最佳控制,提高金属回收率,降低成本,改善产品质量和放大设计所需数学模型提供数据,国外十分重视湿法冶金各单元过程的化学研究,在某些方面已取得了新的进展。 Since the seventies of this century, with the development of hydrometallurgy industry, the wet method is very important in foreign countries to achieve the best control of the process, increase the metal recovery rate, reduce the cost, improve the product quality and amplify the mathematical model required by the design The chemical research of metallurgical unit processes has made new progress in some aspects.
