Based on samples of nickel-cobalt-copper matte first produced by TMC in 2021, the Extractive Metallurgy team at SGS tested TMC's efficient flowsheet to process high-grade nickel-copper-cobalt matte directly to high-purity cobalt sulfate without making cobalt metal, while producing fertilizer byproducts instead of solid waste or tailings. This milestone follows last month's successful production of nickel sulfate, a key raw material input used in the production of energy-dense electric vehicle batteries. In ...
