iron carbonate cake is a solid waste generated from uranium milling

  • Uranium processing | Britannica

    Uranium processing, preparation of the ore for use in various products. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals
