Electrowinning of iron from sulphate solutions

2008-2-1  The reactions taking place in an electrolytic cell when depositing iron from a solution containing iron sulphate, can be written as follows: (2a) At the cathode: Fe ++ + 2e = Fe (2b) H + + e = 1/2 H 2 (2c) Fe +++ + e = Fe ++ (3a) At the anode: SO 4 −− −

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.

Removal of iron from cobalt sulfate solutions by ion

2007-4-1  The pH of the solution has a significant effect on the separation of iron (III) and cobalt and from a mixed sulfate solution containing 20 mg/L iron (III) and cobalt. On the other hand, loading of cobalt from a concentrated solution of 50 g/L results in suppression of the loading of iron even at low pH values.
