The fines produced in crushing or slimes contained in the ore interfere with leaching and lowers extraction due to channeling of solution through the coarser segregated particles. Channeling can be reduced by methods to insure uniform mixing and charging of leach tanks. Excess fines often must be removed and treated separately by agitation.
