各相关单位:近年来,湿法冶金技术凭借其低成本、高回收率的特性得到了越来越广泛的应用和长足的发展。然而,随着当前对节能环保和重金属污染的日趋重视,湿法冶金在迅速发展的同时也暴露出一定的局限性和需要重视并改进的一系列问题,例如:开放式生产环节的环境危害和人员健康威胁、低浓度金属溶液的提取困难、多种伴生金属的分离纯化提取工艺繁琐、节能降耗技术与设备的研发等等,以促使湿法冶金工艺不断 Relevant units: In recent years, hydrometallurgy technology has been applied more and more extensively due to its low cost and high recovery rate. However, with the current emphasis on energy saving and environmental protection and heavy metal pollution, rapid development of hydrometallurgy also reveals certain limitations and a series of problems that need to be emphasized and improved, such as the environmental hazards of open production processes and Personnel health threats, low concentration of metal solution extraction difficulties, a variety of associated metal separation and purification process cumbersome, energy saving technology and equipment research and development, etc., in order to promote hydrometallurgical process
