Abstract

The invention relates to a method for smelting non-ferrous metal sulfides (13) in a suspension smelting furnace and to a suspension smelting furnace. The suspension smelting furnace comprises at least one injection means (18) for injecting at least one of fluid (19) and pulverous matter (20) into a settler (2) of the suspension smelting furnace from at least one of a first side wall structure (8) and a second side wall structure (9) of the settler (2) so that fluid (19) and/or pulverous matter (20) is injected into the settler (2) above a top surface (16) of a layer of melt (15) in the settler (2).
