Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) ... This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities. The copper matte created by the smelting furnace contains 58-60% copper.
Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit.
Copper slag is the by-product of the copper pyrometallurgy process, with an annual output of about 68.7 Mt from the global copper industry (Sharma et al., 2017). Copper slag can be disposed when copper content in slag is reduced to below 0.5 wt%.

leaching of copper from copper slag is shown in Figure 1. RESULTS AND DISCUSSION Table I gives the chemical composition of the copper slag; the results are obtained by using X-ray fluorescence analysis. It can be observed from the analysis that iron, silicon and calcium are the major constituents. Table I. Chemical analysis of copper slag.
Copper sulfide and iron oxide can mix, but when sufficient silica is added, a separate slag layer is formed. Adding silica also reduces the melting point (or, more properly, the liquidus temperature) of the slag, meaning that the smelting process can be operated at a lower temperature. The slag forming reaction is: FeO + SiO 2 → FeO.SiO 2
