FIELD: non-ferrous pyrometallurgy, in particular, small-scale or average-scale production of matte or metal with the use of mobile equipment in poorly settled regions with non-existent or weakly developed infrastructure.
SUBSTANCE: method involves melting with the use of oxygen-containing blast gas; converting; depleting slag in gasifier; reducing gases from melting process and converting with hot gases from gasifier. Oxygen-containing blast gas used is exhaust gas of energetic gas turbine unit operating on natural gas or gas generating gas from coal gasification. Gas used for gas turbine unit is gas generating gas from bath coal gasification produced on slag depletion. Flow line has melting bubbling furnace, converter, gasifier for slag depletion, gas turbine unit with system of gas discharge channel connected through branches with tuyeres of melting furnace, converter and gasifier. Each of said branches is equipped with pressure regulator and flow regulator.
EFFECT: reduced costs for performing method owing to employment of mobile equipment.
