    Abstract: The invention relates to a method and to an arrangement for refining copper concentrate (1). The arrangement comprises a suspension smelting furnace (2) comprising a reaction shaft (5), and a settler (6). The reaction shaft (5) is provided with a concentrate burner (8) for feeding copper concentrate (1) such as copper sulfide concentrate and/or copper matte and additionally at least reaction gas (9) into the reaction shaft (5) to obtain a blister layer (11) containing blister and a first slag layer (12) containing slag on top of the blister layer (11) in the settler (6), and a slag cleaning furnace (3). The arrangement comprises feeding means (16, 18, 23) for feeding blister from the blister layer (11) in the settler (6) and for feeding slag from the first slag layer (12) in the settler (6) into the slag cleaning furnace (3).

    Abstract: The invention relates to an arrangement for feeding fine-grained matter to a concentrate or matte burner (1) of a suspension smelting furnace (2). The arrangement includes a screw conveyor (3) comprising a tube means (4) having an inlet opening (6), an downward-facing outlet opening (7), and a helical screw (8) for moving fine-grained matter from the inlet opening (6) to the downward-facing outlet opening (7). The downward-facing outlet opening (7) is provided with a distribution means (10). The distribution means (10) has a free end (11) configured for feeding fine-grained matter into the downward-facing outlet opening (7). The helical screw (8) of the screw conveyor (3) extends from the direction of the inlet opening (6) at least partly over the downward-facing outlet opening (7).
