Copper slag is a by-product created during the copper smelting and refining process. Copper slag is a by-product obtained during the production of copper metal, which can be used as pozzolana in the production of cementing materials. Recycling copper slag to recover metals has been focused on copper recovery.
Technological scheme for copper slag processing is proposed. • The scheme includes thermal oxidation, hydrothermal treatment, gelling of the liquid and drying. • Process optimization was done. • Extraction of the silicon was over 70%.
The process includes three operations similar to copper and nickel slag production: 1. roasting, 2. smelting, and 3. converting. Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced.
Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.

Discard slag may contain 0.5–0.7% copper and is frequently used as construction material or for sandblasting. Leaching processes produce residues, while ef-fluent treatment results in sludges, which can be sent for metals recovery. The smelting process typically produces less than 3 tons of solid waste per ton of copper produced.

Granulated copper slag is more porous and therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size (Emery, 1986, Hughes and Haliburton, 1973).
