A burner for a flash smelting furnace. The burner includes an injector having a sleeve for delivering pulverous feed material to the furnace and having a central lance within the sleeve to supply compressed air for dispersing the pulverous feed material in the reaction shaft of the furnace. The central lance has an annular slot at its tip for creating a substantially continuous air curtain.
