A gravity separation process is a physical separation method based on the density differences between ore particles. It involves several forces like gravity and fluid resistance (i.e. water in case of this project). True densities of Mn bearing minerals are around 3.0-3.5 g/cm3 whereas densities of the pisolites are around 2.2-2.4 g/cm3.
