Blister copper was first produced in the pilot furnace of the Metallurgical Research Centre at Pori in 1969 and the first commercial plant for direct blister production was commenced in 1978 in Poland. This paper is a survey on the effect of oxygen potential or matte grade on the metallurgy of smelting copper concentrates in a flash smelting ...
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of % purity. Copper can be recycled indefinitely without the base metal being compromised ...
The matte produced by the flash smelting furnace is transferred to the Converter furnace. Oxygenenriched air is blown into the Converter furnace to oxidize the matte further to create blister copper with a grade of approximately 99%. Reaction in the converter Cu 2 S・FeS + SiO 2 + O 2 → Cu + 2FeO・SiO 2 + SO 2 + Reaction heat
