The copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper losses of most plants in the discarded slag limited between 0.8 wt.% and 1.0 wt.% (Coursol et al., 2012). However, the final copper slag still contains large amounts of valuable …

Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about 1.5 million tons of copper slag are generated annually in Korea. The oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia …

The corrosion of the refractory in the static test starts when the slag softens (~1350 °C), and the melt attacks the weaker part of the structure first, i.e., the matrix. The smaller particles are dissolved first, and even the aggregates may be attacked; thus, the matrix completely reacts and disappears.
