The invention relates to a method for producing blister copper, according to which method copper concentrate (5), flux (6) and oxygen-enriched air (7) are fed together into a suspension smelting furnace (1), such as a flash smelting furnace, so that there are created at least two molten phases, such as a white metal phase (11) and a slag phase (10); and that the white metal is oxidized after the suspension smelting furnace in at least one oxidizing reactor (12).

L'invention concerne un procédé servant à produire du cuivre boursouflé et consistant à introduire dans un four de fusion en suspension (1), tel qu'un four de fusion éclair, un concentré de cuivre (5), un fondant (6) et de l'air enrichi en oxygène (7), de façon à créer au moins deux phases de fusion, telles qu'une phase de métal blanc (11) et une phase de scorie (10) et à oxyder le métal blanc après son passage dans le four de fusion en suspension dans au moins un réacteur d'oxydation (12).
