Abstract In the dumps of power plants of the Republic of Kazakhstan, only from the combustion of Ekibastuz coal, ~ 300 million tons of ash have been accumulated, with an annual release of up to 30 million tons. Up to 200 g/t of gallium, germanium, 1 g/t of gold, 4% of zinc, 1% of lead, 0.3% of cadmium and other elements are lost with ash. The work is aimed at unit creation to obtain hydrogen-enriched water gas from ekibastuz coal with the production of Zn, Ga, Ge sublimates, copper-containing cast iron, slag wool and/or cast stone, when joint processing of iron-zinc-contained slag and ash-cinder wastes of thermal power plants.
