  Separation of copper from cobalt in sulphate solutions by using CaCO3 ...

  2016915 · Lime neutralization is widely used to precipitate heavy metals including copper and cobalt from wastewater. Limestone (calcium carbonate: CaCO 3) is too stable to be used directly for this purpose. Grinding of CaCO 3 in the solutions of copper and cobalt sulphate was conducted to raise its reactivity. During the mechanochemical activation, …
