Copper Smelting Process Furnaces Used, By Products, and

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 99.9 purity. Copper can be recycled indefinitely without the base metalpromised

Copper Smelting an overview ScienceDirect Topics

Copper Production. W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching oxide and

Copper Scrap an overview ScienceDirect Topics

Thus copper containing scrap is to large extent used as a coolant in ore based copper production. The matte converting process is normally divided into two main stages: the slag making stage and the copper making stage. In the slag making stage, impure scrap with a lower copper content can be used, whereas in the copper smelting stage, pure copper scrap is used, especially spent anodes from
