Blister Copper an overview ScienceDirect Topics

Blister copper. The unrefined copper of about 98.5% purity produced from the converting step of copper smelting. Calcium ferrite slag. A slag based on CaO that contains FeO and Fe 2 O 3, which can absorb highly oxidized iron and thus is used in continuous copper converting under higher oxygen partial pressures than in conventional converting processes.
