Electrowinning of iron from sulphate solutions

2008-2-1  In recent years very little has been published in the literature about electrowinning of iron from mineral ores in acid electrolytes. However, a related problem has been addressed in connection with the recovery of Zn and Fe from spent pickling solutions (Csicsovszki et al., 2005).Here iron deposition from hydrochloric solutions was studied in a two-compartment cell using an ion-exchange membrane.

Electrowinning of iron from sulphate solutions

The present paper describes pilot plant operation of the crucial step of this process, which is electrowinning of iron from a sulphuric acid solution, using iron starting sheets and lead anodes surrounded by a diaphragm. High purity iron was produced, with a current yield of 85% and a power consumption of 4.25 kWh/kg iron.

Electrowinning of Iron from Spent Leaching Solutions

2019-10-24  1. Introduction. A South African mining group is investigating the use of electrowinning (EW) to recover iron and H 2 SO 4 from an iron sulphate waste solution produced during metal beneficiation. For the purpose of this paper, the term electrowinning, as is commonly applied for this process, is used throughout the paper.
