Lead-zinc smelting slag (LZSS) is an industrial waste which is considered as hazardous waste due to the presence of heavy metals (Pb, Zn, Cr and Cu). These heavy metals can be leached into the ecosystem to pollute the environment. Moreover, LZSS is utilized as the preparation of alkali-activated materials (AAM) because it is rich in ...
Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly …
A recovery ratio of 97.47% Cu in the copper phase was obtained at a lower temperature and shorter duration compared to the pyrometallurgy methods. Wang et al. [ 104, 105] also attempted to separate fine copper droplets from copper matte smelting slag by utilizing super-gravity.
Steel slag is the by-product during the separation of molten steel from impurities in the steel-making furnace. The basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag are three major types of SS produced in the steelmaking processes.As drawn in Fig. 2, BOF slag and EAF slag are both produced …
