Guo et al. 2016 developed a new technology to improve the beneficiation of copper and iron components from copper slag, by modifying the molten slag to promote the mineralization and grain growth of the valuable compounds. Results showed that, under the proper conditions, the copper grade of the rougher stage increased from 6,43 to 11,04 ...
The chemical compositions of copper slag used in this study are given in Table 1. The total iron content of copper slag is 39.85, and the content of SiO 2, Cu, Pb and Zn are 30.81, 0.33, 0.22 and 2.81, respectively. The minerals of copper slag determined by X-ray diffraction XRD are mainly fayalite and magnetite, as shown in Fig. 1.
