Flotation Of Minerals

Floatation SlideShare

True flotation dominates the recovery of the valuable minerals and the other two decide the separation efficiency between the valuable and the gangue FLOTATION process can be applied to relatively fine particles because if the particles are coarse and heavy their weight will be greater than the adhesion between the particle and the air bubble and the particle will detach from the
