Cleaner recycling of iron from waste copper slag by using …

2019-4-20 · There are two main ways for recovering iron from the copper slag: (i) first, Fe 2 SiO 4 is oxidized to Fe 3 O 4, and then the Fe 3 O 4 enriched concentrate can be obtained by magnetic separation (Zhang et al., 2005).The iron recovery in concentrate obtained by this way is low, and the Fe 3 O 4 concentrate needs to be reduced again to obtain metallic iron. (ii) Copper slag is …

Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica. These exist in copper slag mainly in the form of fayalite (2FeO ·SiO2).
