  Mineral Processing | SpringerLink

  Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral engineering in China. It was later …
