Abstract

Wynalazek dotyczy sposobu rafinacji koncentratu miedzi. W sposobie koncentrat miedzi (1), topnik (2) i gaz reakcyjny (3) dostarcza się razem do szybu reakcyjnego (5) pieca do wytapiania zawiesinowego (4) na przykład do szybu reakcyjnego (5) zapłonowego pieca do wytapiania, i w piecu do wytapiania zawiesinowego (4) powstają oddzielne fazy, to jest miedź konwertorowa (13) i żużel (14). W sposobie żużel (14) z pieca do wytapiania zawiesinowego doprowadza się do pieca elektrycznego (16) i żużel (14) z pieca do wytapiania zawiesinowego poddaje się w piecu elektrycznym (16) działaniu środka redukującego tak, że w piecu elektrycznym (16) powstają oddzielne fazy, to jest dolna faza metalu (17) i żużel odpadowy (18); otrzymany metal (17) usuwa się z pieca elektrycznego (16), metal (17) z pieca elektrycznego granuluje się i otrzymuje się granulowany metal (22) z pieca elektrycznego, a granulowany metal (22) z pieca elektrycznego dostarcza się do szybu reakcyjnego (5) pieca do wytapiania zawiesinowego (4).The invention relates to a method for refining copper concentrate. In the process, the copper concentrate (1), the flux (2) and the reaction gas (3) are fed together into the reaction shaft (5) of the suspension smelting furnace (4), for example, into the reaction shaft (5) of the flash smelting furnace, and in the reaction In suspension smelting (4), separate phases are formed, i.e. blister copper (13) and slag (14). In the process, the slag (14) from the suspension smelting furnace is fed to the electric furnace (16), and the slag (14) from the suspension smelting furnace is treated with a reducing agent in the electric furnace (16) so that in the electric furnace (16) separate phases, i.e. lower metal phase (17) and waste slag (18); the resulting metal (17) is removed from the electric furnace (16), the metal (17) from the electric furnace is granulated, and the granulated metal (22) from the electric furnace is obtained, and the granular metal (22) from the electric furnace is fed to the reaction shaft ( 5) a suspension smelting furnace (4).
