Extraction of iron from copper-plant slag SpringerLink

2017-1-5  In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification products of carbon in ...

RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG

Copper slag is a by-product obtained during smelting and refining of copper.

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 reduced by fossil ...
