Abstract

Изобретение касается способа получения черновой меди, в соответствии с которым медный концентрат (5), флюс (6) и обогащенный кислородом воздух (7) подают совместно в печь (1) взвешенной плавки, такую как печь для плавления во взвешенном состоянии, с тем, чтобы получить там по меньшей мере две фазы расплава, такие как фаза (11) белого металла и фаза (10) шлака, при этом после печи взвешенной плавки белый металл окисляют по меньшей мере в одном реакторе (12) окисления.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a method for producing blister copper, according to which copper concentrate (5), flux (6) and oxygen-enriched air (7) are fed together to a suspended smelting furnace (1), such as a suspended smelting furnace, to get there at least two melt phases, such as the white metal phase (11) and the slag phase (10), while after the suspension smelting furnace the white metal is oxidized in at least one oxidation reactor (12). The international application was published together with an international search report.
