Abstract

A process and device to be used in the flash smelting of sulphide ores or concentrates is disclosed, wherein molten matte is fed, possibly after granulation, into an oxidation zone together with air and/or oxygen, whereafter the hot roasting gases are fed into the upper part of the reaction zone of a flash smelting furnace together with fuel and ore or concentrate. The reaction space or bed in the oxidation furnace is cooled or the air and/or oxygen is pre-heated before it is fed into the oxidation zone in order to control the oxidation capacity of the oxidation furnace and the smelting capacity of the flash smelting furnace and to relate the capacities to each other.
