The invention relates to an apparatus for feeding finely divided solids, containing at least sulphidic metal concentrate, and oxygenous oxidizing gas into a suspension smelting furnace, said apparatus comprising elements for conducting solids and oxidizing gas into the suspension smelting furnace. According to the invention, in the feed orifice (7) of the suspension smelting furnace through which solids (2) and oxidizing gas (3) are fed into the reaction chamber (1) of the suspension smelting furnace, there is installed a suspension creation chamber (5,11) for a suspension containing solids (2) and oxidizing gas (3), in which chamber the solids (2) and at least part of the oxidizing gas (3) can be mixed to form a suspension before they flow into the reaction chamber (1) of the suspension smelting furnace.
An apparatus for feeding finely divide solids, containing at least sulphidic metal concentrate, and oxygenous oxidizing gas into a suspension smelting furnace, said apparatus comprising elements for conducting solids and oxidizing gas into the suspension smelting furnace, a feed orifice of the suspension smelting furnace through which solids and oxidizing gas are fed into a reaction chamber of the suspension smelting furnace containing a suspension creation chamber for a suspension containing solids and oxidizing gas in which chamber the solids and at least part of the oxidizing gas can be mixed to form a suspension before they flow into the reaction chamber of the suspension smelting furnace so that the suspension creation chamber is, with respect to a concentrate supply conduit, connected to the feed orifice of the suspension smelting furnace at its opposite end in order that the suspension formed of solids and oxidizing gas has free access to flow from the suspension creation chamber directly to the reaction chamber of the suspension smelting furnace.
