ABSTRACT:
The present invention relates to a method and apparatus for treating sulphide concentrates of sulphide ores in order to produce raw metal in one and the same process unit (1). According to the invention, the molten matte (5) received from suspension smelting is solidified (7) and, if necessary, crushed (8) and ground (9), whereafter the solid matte (5) is returned into the process unit (1) through the converting shaft (10) located therein. In the converting zone (15) the matte (5) is converted into raw metal (12) by means of a two-phase method. The exhaust gases both from the smelting zone (16) and from the converting zone (15) are discharged through a common uptake shaft (4). Moreover, the slags (6,11) from both zones can be discharged through the same tap hole (17), whereas the matte (5) and the raw metal (11) are advantageously removed from the process unit (1) each through a specific individual tap hole (18,19).
