Abstract: An extensive study of chemical and mineralogical composition of the ash and slag waste of power production enterprises, sampled from landfills of CHP-2 in Vladivostok was carried out. The data on the content and forms of finding gold and silver in the ash and slag waste of CHP-2 in Vladivostok are given. The elemental and mineral composition of studied samples selected from dumps of power production enterprises is given. Difference in the mineral composition of heavy and light fractions of ash and slag waste concentrate is shown. The data on the mineral composition of the micro-spheres contained in the ash and slag waste of CHP-2 in Vladivostok are shown.
