Hydrometallurgical Processing of Low-Grade Sulfide Ore

2018-10-7 · Early studies of hydrometallurgical methods for processing of copper-nickel ores from theMurmansk region deposits were launched in the 70 s of the previous century. For referencingpurposes, the main types of disseminated ores from the deposits Zhdanovsky, Kaula, SopchinskyPlast, and Lovnoozersky were selected. The metal content varied: 0.46–1.49% Ni and 0.01–0.62% Cu.In the first experiments, the solution containing 150 g/L of H2SO4and 135 g/L of NaCl was used as aleaching reagent. The laboratory and further large-scale tests proved the possibility of undergroundmetal leaching from the Lovnoozersky deposit ores.
