| Popis: | The problem of disposal of ash and slag waste in Russia and in the world is very urgent. Ash dumps occupy vast areas, damaging the ecosystem. At the same time, these wastes are independent deposits of rare and rare-earth metals, which are necessary for the production of modern high-tech devices. The efficiency of flotation and chemical methods of concentration of materials in order to extract valuable components are evaluated in the paper. The composition of the initial ash and slag samples and the resulting products of their processing were analyzed using IR spectroscopic and optical emission methods. |
