HYDROMETALLURGY

Hydrometallurgy aims to compile studies on novel processes, process design, chemistry, modelling, control, economics and interfaces between unit operations, and to provide a forum for discussions on case histories and operational difficulties.Topics covered include: leaching of metal values by chemical reagents or bacterial action at ambient or elevated pressures and temperatures; separation of solids from leach liquors; removal of impurities and recovery of metal values by precipitation, ion exchange, solvent extraction, gaseous reduction, cementation, electro-winning and electro-refining; pre-treatment of ores by roasting or chemical treatments such as halogenation or reduction; recycling of reagents and treatment of effluents.

湿法冶金旨在汇编有关新工艺、工艺设计、化学、建模、控制、经济学和单元操作之间接口的研究，并为讨论案例历史和操作困难提供一个论坛。主题包括：通过化学试剂或细菌作用在环境或高温压力下浸出金属值；从浸出液中分离固体；通过沉淀、离子交换、溶剂萃取、气体还原、胶结、电积和电精炼去除杂质和回收金属值。通过焙烧或化学处理（如卤化或还原）对矿石进行预处理；试剂回收和废水处理。
