Process for copper converting - Outotec Oyj

The process for converting a copper sulphide matte to blister copper, is achieved by adding the copper sulphide matte and flux to a suitable agitated slag phase; and injecting, from a discharge tip at the lower end of a top-submerged lance, an oxidizing gas suitable for reacting with the matte to produce blister copper which forms or adds to a continuous blister copper phase below the slag phase.

Exergy in Copper Converting and Its Relation to SO2 ...

2016-5-12 · Copper pyrometallurgy comprises a sequence of processing steps: toasting, smelting, converting, fire refining, and anode casting. Of these stages, perhaps converting is the most critical one since during this stage, both the iron and the sulfur from copper ores are eliminated, and a metallic product with nearly 99 wt% copper is obtained.
