The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.

該雜志的目的是迅速出版專題論文，介紹有關礦物加工和萃取冶金領域的最新發展。其廣泛的研究和實踐(操作)主題包括物理分離方法，如粉碎，浮選濃度和脫水，化學方法，如生物，水，和電冶金，分析技術，過程控制，模擬和儀器，和礦物學方面的加工。環境問題，特別是與可持續發展有關的環境問題也將得到強有力的討論。
