Minerals Free Full-Text A Brief Review of Micro-Particle MDPI

Froth flotation has been the most widely used approach for treating complex low-grade and finely disseminated ores. Flotation pulp consists of micro-particles with a certain grinding fineness, which is generally expressed as the mass ratio (%) of less than 0.074 mm/the total grinding product (the grinding fineness depends on the target Ore Composition. Ores generally consist of ore minerals and gangue minerals. Ore minerals, also called useful minerals, refer to metal or nonmetal minerals that can be utilized in ores, such as chalcopyrite, bornite, chalcocite, malachite in copper ores, and serpentine asbestos in asbestos ores. Gangue minerals, also called useless Ore, Composition and Classification of SpringerLink
