Sep 21, 2012· Smelters using slag milling and flotation for slag cleaning generally operate under conditions where most of the copper in slag would tend to form Cu 2 S upon cooling, although some metallic copper may still form via reaction 3. 7 Ideally, the slag should be slow cooled to allow most of the copper to form larger matte prills (over 30 μm in size), leading to minimal copper levels in the slag .

Refining. Even though copper blister is 99% pure copper, it still contains high enough levels of sulfur, oxygen, and other impurities to hamper further refining. To remove or adjust the levels of these materials, the blister copper is first fire refined before it is sent to the final electrorefining process.

Copper slag usually has a low content of CaO; granulated copper slag exhibits pozzolanic properties as CaO content in copper slag increases, it can exhibit cementitious properties. Studies [812] indicated that a copper slag, which contains approximately 19% CaO, show a good cementitious property under the activation of NaOH.
