EXTRACTION METHOD OF METALS AT THE GASIFICATION OF SOLID FUEL IN A POLYFUEL GAS GENERATOR Russian patent published in 2018 - IPC C10J3/57 C22B5/10 

FIELD: technological processes.

SUBSTANCE: invention relates to the complex processing of carbonaceous materials, such as coal, peat, combustible shale, carbonaceous technogenic materials, such as waste coal, wood waste, solid municipal waste, and can be used in power engineering, chemical industry, ferrous metallurgy. Method for recovering metals in the gasification of solid fuel in a polyfuel gas bubble-type gas generator involves feeding solid fuel into a molten oxide bath, filling the side gaseous oxidizer with jets, removal of condensed reaction products in a liquid form, withdrawal and cooling of gaseous reaction products. Solid fuel is fed into the oxide melt in the form of briquettes containing solid fuel and iron-containing material, in which case hematite ore is used, wherein the iron-containing material is introduced in an amount providing a weight ratio of the amount of the solid iron fuel injected and present in the sol to the total amount of the main slag-forming oxides of silicon, aluminum, titanium, calcium and magnesium present in the solid fuel ash, binder and iron-containing material, within the range of 0.10–0.75.

EFFECT: decrease in the removal of dust, increase the degree of extraction of metals in the alloy.
