  • Recovery of cobalt and copper through reprocessing of

    It is an attempt oriented towards the lowering of the mineral processing industry footprint on the environment through the reprocessing of tailings from the beneficiation of oxidised ores of copper and cobalt . As the matter of fact, it is expected that the reprocessing of tailings can enable minimising the release of pollutants to watercourses

  • Mineral processing Wikipedia

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

  • Reprocessing Gold Tailings by Gravity Methods

    A preliminary test has been carried out on a superpanner, on the tailings as such, and it has shown that the concentrates consist mainly of coarse particles containing mixed grains of gold and quartz, iron oxides and some tiny grains of gold and pyrite however, very small grains of gold are entrained with the slimes into the residue.
