The article contains data on the results of synthesized blowing agents SK-1, SK-2 used in the enrichment and flotation of non-ferrous and precious metal-containing coals from deposits of the Republic of Uzbekistan. Di- and triethanolamine are the bases offoaming agents, which were obtained under similar conditions. The reagents effectively reduce the surface tension of the solutionto σ= 28.5 MN/m and have a stable foaming capacity ѵ=265 ml; surface tension of reagent SK-2 σ= 30.5 MN/m; foamingcapacity ѵ=260 ml. The stalagmometric method was used to determine the emulsifying properties of the foaming agent obtained.A scheme for the extraction of metals has been developed, consisting of: crushing, the size of coal is brought to the opening ofgrains of minerals and sulfur; firing in an oven at a temperature of 500o С, volatilization of carboxyl groups and sulfurcomponents, as a result of which the metals pass into the sulfate group; grinding process - coal in ball mills is brought to aparticle size of 150 microns; leaching process - extraction of metals and their compounds into solution using HCl and HNO3,then the metals are separated and isolated; The proposed blowing agents SK-1, SK-2 allow the integrated use of natural coal andcan solve the important problem of ash and slag waste disposal and significantly reduce emissions of toxic elements into theatmosphere.
