    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).
