    Abstract: A method for recovery of evaporable substances comprises melting (210) of a material comprising evaporable metals and/or evaporable metal compounds into a molten slag. The molten slag is agitated (212) by a submerged jet of hot gas. The hot gas is controlled (214) to have an enthalpy of at least 200 MJ/kmol, and preferably at least 300 MJ/kmol. At least a part of the evaporable metals and/or evaporable metal compounds are fumed off (216) from the molten slag. An arrangement for the method is based on a furnace with a plasma torch submerged into molten slag in the furnace.

    Abstract: An iron production furnace equipment (1) has a melting reactor (2) into which iron oxide-containing raw material (4) and slag formers (5) are added. A melter arrangement (22) melts the iron oxide-containing raw material and transforms the melted raw material into liquid slag (6) A smelting reduction reactor (3) is connected to the melting reactor by a slag transfer arrangement (10). The smelting reduction reactor comprises a heater arrangement (30) for heating the slag. Means (32) for supplying a reductant (7) for reducing the iron oxide in the slag into a liquid iron melt (8) and for producing a combustible gas mixture (11) comprising at least one of CO and H 2 . A gas connection (12) is connected between the smelting reduction reactor and the melter arrangement. The melter arrangement in turn comprises a combuster (28) combusting the gas mixture. The combustion heat is used for purpose of melting.
