METHOD TO CONCENTRATE SCATTERED ELEMENTS Russian patent published in 2015 - IPC C22B58/00 C22B41/00 C22B1/00 C22B7/02 

FIELD: power engineering.

SUBSTANCE: method to concentrate scattered elements included into composition of solid carbon-containing mineral, includes sublimation of volatile scattered elements when burning the solid carbon-containing mineral to produce the first sublimate in the form of enriched fly ash. Then the second sublimation is performed by burning the first sublimate in the form of a fuel water-coal suspension with a semi-coke dispersed phase to produce the second sublimate. Prior to finish catching of the concentrate they perform the third sublimation by combustion of the second sublimate in the form of a fuel emulsion with a dispersed phase in the form of a liquid pyrolysis fraction. At the same time semi-coke and liquid fraction are produced as a result of pyrolysis of initial solid carbon-containing mineral.

EFFECT: production of additional commercial product containing Ga, Ge, As, in process of industrial generation of thermal or electric power.
