Title (EN) METHOD FOR REFINING SULFIDIC COPPER CONCENTRATE
(FR) PROCÉDÉ DE RAFFINAGE DE CONCENTRÉ DE CUIVRE SULFURÉ
Abstract:
(EN) The invention relates to a method for refining sulfidic copper concentrate (1). The method comprises feeding sulfidic copper concentrate (1) and oxygen- bearing reaction gas (2) and slag forming material (3) into a reaction shaft (4) of a suspension smelting furnace (5), collecting slag (7) and blister copper (8) in a settler (9) of the suspension smelting furnace (5) to form a blister layer (10) containing blister copper (8) and a slag layer (11), and discharging slag (7) and blister copper (8) separately from the settler (9) of the suspension smelting furnace (5), so that slag (7) is fed into an electric furnace (12). The method comprises by feeding a part of the sulfidic copper concentrate (1) into the electric furnace (12).
(FR) Cette invention concerne un procédé de raffinage de concentré de cuivre sulfuré (1). Le procédé comprend l'introduction d'un concentré de cuivre sulfuré (1) et d'un gaz de réaction contenant de l'oxygène (2) et d'un matériau de formation de laitier (3) dans une cuve de réaction (4) d'un four de fusion en suspension (5), la collecte du laitier (7) et de cuivre blister (8) dans un décanteur (9) du four de fusion en suspension (5) pour former une couche brute de coulée (10) contenant du cuivre blister (8) et une couche de laitier (11), et l'évacuation du laitier (7) et du cuivre blister (8) séparément à partir du décanteur (9) du four de fusion en suspension (5), de sorte que le laitier (7) soit introduit dans un four électrique (12). Le procédé comprend en outre l'introduction d'une partie du concentré de cuivre sulfuré (1) dans le four électrique (12).
