  • How Is Cobalt Extracted?

    Cobalt is extracted from the nickel or copper through solvent extraction, which is separating compounds based on their solubility in two immiscible liquids, such as an organic solvent and water. Hence, it extracts the cobalt substance from one liquid into another liquid phase.
