After copper slag is generated, it is essential to characterize its properties in detail for subsequent treatment. In the third article, entitled "Mineralogical Characterization of Copper Slag from Tongling Nonferrous Metals Group China," Tiejun Chun et al. investigated the mineralogical characteristics of a typical copper slag (40.21 wt.% Fe, …

Globally a large volume of copper slag (Table 1) is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [9].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [6].Table 1 illustrates the magnitude of …

Copper Slag (CS) is a solid waste produced during the industrial smelting of copper (Gorai et al., 2003).The current pyrometallurgical copper smelting process is mainly through the Ausmet furnace (Fig. 1); the furnace slag goes through the flotation process to obtain copper matter, yielding a composition of CS corresponding to 30–40 % of Fe, …

Sarfo et al. (2017) carried out carbothermal reduction process of copper slag (from the United States) by mixing 12.5% carbon with copper slag and reacting at 1420 °C for 0.75 h. The initial copper slag is reduced to low-grade pig iron with the recovery efficiency of up to 90% (Sarfo et al., 2017). However, non-ferrous metal elements can …
