Draslovka has acquired the environmentally friendly GlycineGlycine LeachingLeaching TechnologyTechnology (GLT) to offer alternative hydrometallurgical solutions to the mining industry for recovering base and precious metalsMetals compared with traditional methods. This study presents an innovative alkaline leachingLeaching process, namely GlyLeach™, to extract Ni and Co from a flotationFlotation secondary cleaner tailingsTailings sample which would normally be considered as waste due to lack of an economical hydrometallurgical processHydrometallurgical processes. This material is rich in magnesiumMagnesium and iron silicates/oxides with 0.4% Ni and 0.01% Co in disseminated sulfide minerals. This paper covers the comprehensive studies involving 2 L tank leach tests and mini pilot runs to evaluate the performance of GlyLeach™ for extracting Ni and Co from this low-grade tailingsTailings sample. Once leached, the metalsMetals in solution were recovered via NaHS precipitationPrecipitation process which converted the Ni and Co in solution to a mixed sulfideMixed sulfide precipitate (MSP) while glycineGlycine previously complexed with these base metalsMetals was released back into solution to be recycled to leach fresh feed. LeachingLeaching tests showed 50–60% Ni extractionsNi extraction and over 33% Co extractionsExtraction under optimal leachingLeaching conditions, i.e., pH 10, 35% solids, 45–50 °C, oxygen flow rate at 0.1 L/min. The NaHS precipitationPrecipitation process achieved 98% Ni recovery as MSP with minimal impact on the free glycineGlycine concentration. This process has the potential to generate additional revenue from the flotationFlotation tailingsTailings “waste” stream that will not only increase the recovered metalMetals from such ores but also improve the economics of any flotationFlotation operation.
