Characteristics and utilisation of copper slag—a review ...

Since copper slag has a low content of CaO, granulated copper slag exhibits pozzolanic properties (Deja and Malolepszy, 1989, Douglas and Mainwaring, 1985). As CaO content increases or under the activation of NaOH it can exhibit cementitious properties and can be used as partial or full replacement for Portland cement.

Copper - essentialchemicalindustry.org

Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.
