CHAPTER-7 GRAVITY CONCENTRATION OF IRON ORE
Gravity separation of two minerals, with different specific gravity, is carried out by their relative movement is response to force of gravity and one or more other forces. Normally one of the forces is the resistance to motion by a viscous fluid e.g. water. So, besides the specific gravity the factors like size, shape and weight of the particles affect the relative movement and hence the
