Abstract

Oxidation-reduction potential of a beneficiated ore slurry prepared for flotation is determined under optimum flotation conditions and the slurry thereafter is treated with beneficiating chemical in quantity controlled to the range of the pre-determined oxidation-reduction potential. [US3883421A]
