Extraction of iron from copperplant slag SpringerLink

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 ...

Removal of Arsenic During Iron Extraction from Waste

Removal of Arsenic During Iron Extraction from Waste

Sep 02, 2020 Owing to the excessively high arsenic content present in iron extracted from copper smelting slag, we propose a new arsenic removal process in this paper. The results indicate that arsenic sulfides in copper smelting slag can be significantly removed at 1100 C in an N 2 atmosphere, leading to a 0.15 residual arsenic content.
