• Mineral Processingan overview ScienceDirect Topics

    Mineral processing mineral beneficiation or upgradation involves handling three primary types of ROM material which have been blasted fragmented and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
