A method for secondary processing of non-ferrous metals comprises the supply of gaseous fuel, oxidizing agent and also metal part of charge in furnace and it further melting. Blast-furnace and coke gases, and also biogas and shaft methane are used as gaseous fuel. Non-ferrous metals, addition alloy, pressed shaving, spoilage at casting and processing of details are used as charge. Sintered gases in mix with preheated air and partially enriched technical oxygen are used as oxidizing agent.
