Cobalt extraction - Wikipedia

If hydrochloric acid is used then cobalt may be extracted using alamine 336 in meta-xylene. Cobalt can be extracted also using dialkylphosphinic acid. When cobalt carbonate (CoCO 3) is heated (calcined) above 400 °C it decomposes into carbon dioxide (CO 2) and cobalt(II) oxide (CoO) and can be refined as an oxide concentrate (see above).
