濕法冶金旨在匯編有關新工藝、工藝設計、化學、建模、控制、經濟學和單元操作之間接口的研究，并為討論案例歷史和操作困難提供一個論壇。主題包括：通過化學試劑或細菌作用在環境或高溫壓力下浸出金屬值；從浸出液中分離固體；通過沉淀、離子交換、溶劑萃取、氣體還原、膠結、電積和電精煉去除雜質和回收金屬值。通過焙燒或化學處理（如鹵化或還原）對礦石進行預處理；試劑回收和廢水處理。

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.
