Nickel and Cobalt Ores: Flotation
Most of the world’s nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores ...
متن کاملCopper recovery from thickener overflow by electrocoagulation/flotation: optimization of response surface, modeling, and sludge study
The electrocoagulation/flotation process is a novel approach in mining industry that is implemented to return Cu metal to the production cycle, which improves copper recovery and reduces waste water. In this research work, the response surface methodology was applied to optimize the factors effective in Cu metal recovery and sludge volume produced from thickener overflow. To this end, the D-opt...
متن کاملStudy of Cadmium and Nickel Removal from Battery Industry Wastewater by Fe2O3 Nanoparticles
Nickel and cadmium usually enter the environment and water resources through wastewater, released by various industries, and may have adverse effects. The current study employs α–Fe2O3 nanoparticles of 20-40 nm in order to remove nickel and cadmium from the wastewater of Saba Battery Company. Also, it investigates the influence of effective parameters on adsorption process, including pH, contac...

متن کاملEstimation of metallurgical parameters of flotation process from froth visual features
The estimation of metallurgical parameters of flotation process from froth visual features is the ultimate goal of a machine vision based control system. In this study, a batch flotation system was operated under different process conditions and metallurgical parameters and froth image data were determined simultaneously. Algorithms have been developed for measuring textural and physical froth ...
