For the stope designs, a 3.5 m minimum mining width was assumed, and 0.7 m of dilution was applied to the hangingwall and 0.3 m was applied to the footwall of the mineralized zones, using the estimated grade of the waste material. Mining recovery of 81 was assumed to account for expected losses during mining in areas using post pillar cut and ...
In some cases the wastes may contain valuable products that can be recycled, such as heavy metals from a smelter, or solvent from a painting line. The wastes can be used as a raw material for another industrial process - for example, sulphur dioxide collected as sulphuric acid can be used in the manufacture of fertilizers.
Jun 11, 2020 1 Introduction Liquid effluents containing cyanides are generated in some industrial operations such as gold and silver extraction, copperzinc sulfide flotation, iron making, oil refining and metal-plating. Since most aqueous cyanide species are very toxic, these effluents must be treated before discharge into the environment.
