·Mineral liberation and size reduction are the most critical steps before mineral separation Several investigations showed that mineral liberation degree could be affected by ore texture and/or
·The aim of a mineral processing operation is to concentrate a raw ore for the subsequent mineral extraction stage Usually the valuable minerals are first liberated from the ore matrix by comminution and size separation processes crushing grinding and size classification and then separated from the gangue using processes capable of selecting the particles
Mineral processing or mineral dressing is a specialized area in the science of metallurgy that studies the mechanical means of crushing grinding and washing that enable the separation extractive metallurgy of valuable metals or minerals from their gangue waste material
