Ore Sorting vs Dense Medium Separation In Mineral Processing

Benefits Of Dense Medium Separation. While dense medium separation can only rely on density to distinguish valuable materials from waste, it has the advantage of being able to sort a wider range of particle sizes. With ore sorting, the largest particle size should be no more than 3 times that of the smallest particle.
