Copper slag is a by-product formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top. The molten copper slag is then drained off and quenched with water or left in the air to cool. In Singapore, treated and processed copper slag (Mohs Hardness ≥6) is imported from various

This result is mainly attributed to the SCC reduction of the magnetite in converter copper slag, which produces a large amount of CO 2 gas [50]. During metallization reduction, the NaF and Na 3 AlF 6 in SCC react with the CaO and SiO 2 in copper slag and generate new fluorides, such as SiF 4 (m/z = 104) and AlF 3 (m/z = 84). The relevant ...
