Mineral processing is a major division in the science of extractive metallurgy extractive metallurgy has been defined as the science and art of extracting metals from their ores refining them and preparing them for use within extractive metallurgy the major divisions in the order they may most commonly occur are mineral processing or beneficiation hydrometallurgy pyrometallurgy.
Mineral resources can be divided into metal the nonmetal and combustible organic mineral from the perspective of the industry except for purity iron ore with little percentage most of the minerals need to be processed before they can be used because some iron ores are kind of low grade while the main method of processing is beneficiation.
