Outotec Direct Zinc Melting Process liming Outotec

Jul 13, 2017· Zinc production from sulphide concentrates has traditionally been achieved via the Roasting Leaching Electrowinning (RLE) flowsheet. This processing route, however, is associated with the generation of large quantities of hazardous leach residues which cause environmental issues in terms of residue handling and storage, along with increased losses zinc and other metal values.

US4431496A Depolarized electrowinning of zinc Google

A process for electrolytic recovery of zinc wherein metallic zinc is deposited at the cathode while the anode is depolarized through oxidation of iodide ions to iodine, avoiding oxygen evolution at the anode. The iodide ions are chemically regenerated by extracellular oxidation of sulfur dioxide with water to produce iodide ions and hydrogen ions for recycle to the anode compartment.
