Lecture Mineral Beneficiation NPTEL. What constitutes mineral beneficiation? Ore is an aggregate of minerals and contains valuable and gangue minerals .The mineral beneficiation involves separations of gangue minerals from ore and is done in the following two stages: 1. Liberation of valuable mineral by size reduction technologies.
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
