how to remove the iron from zinc sulphate

How do you separate zinc sulphate and iron

Zinc and iron sulphate do react. Zinc is higher in the reactivity series than iron. It can therefore displace sulphate from the iron and 'take' the sulfate.

Recovery of zinc and lead from zinc plant residue

01-11-2004· It was found that the recovery of zinc and iron increased to about 85% and 50%, respectively, with a contact time up to 60 min, and thereafter the extraction remained nearly constant. Similarly, the leaching temperature between 25 and 80 °C had no significant effect on the recovery of zinc or the solubility of lead sulphate.

Purification of nickel sulphate solutions containing

Acidic nickel‐bearing solution containing iron, cobalt, manganese, zinc and copper was processed through a solvent extraction and precipitation technique to obtain a pure nickel sulphate solution. Iron was extracted using 0.2 M Cyanex‐272 (partially neutralised) as the extractant. Stripping of iron from the loaded organic has also been studied.

PROCESS FOR REMOVING IMPURITIES IN THE

In the zinc sulfate solution there is usually contained impurities which were originally existing in zinc ore such as copper, iron, lead, manganese, nickel, cadmium, and cobalt. These impurities not only cause the lowering of the purity of refined zinc but also lower the hydrogen overvoltage at the cathode thereby lowering markedly the efficiency of electrodeposition of zinc.
