Extractive Metallurgy of Nickel, Cobalt and Platinum Group Scrubbing is the chemical removal of nickel that has coextracted with the cobalt. Solvent extraction does not remove impurities, for example, iron, arsenic, lead, manganese and calcium. Solvent extraction is used to extract cobalt from the leaching solution into an organic extractant, leaving a nickelrich, cobaltlean electrolyte.
