iron ore from copper slag

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. 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).

Recovery of Iron from Copper Slag Using Coal-Based

The Fe3O4 and Fe2SiO4 in copper slag were successfully reduced to metallic iron by coal-based direct reduction. Under the best reduction conditions of 1300 °C reduction temperature, 30 min reduction time, 35 wt.% coal dosage, and 20 wt.% CaO dosage (0.75 binary basicity), the Fe grade of obtained iron concentration achieved 91.55%, and the Fe recovery was 98.13%.

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 reduced by fossil ...

Separation of silicon and iron in copper slag by

2020-9-7  Approximately 2.0–3.0 t of copper slag (CS) containing 35%–45% iron is generated for every ton of copper produced during the pyrometallurgical process from copper concentrate. Therefore, the recovery of iron from CS utilizes a valuable metal and alleviates the environmental stress caused by stockpile. In this paper, a new method has been developed to realize the enrichment of iron in CS ...
