    Cobalt extraction - Wikipedia

    The remaining solution (containing approximately equal proportions of nickel and cobalt sulfides), is then adjusted (to a lower temperature and pressure) to precipitate the mixed sulfides and the fluid is concentrated and crystallized into ammonium sulfate ((NH 4) 2 SO 4). The mixed sulfides are pressure leached with air and sulfuric acid.
