Zinc Silicate and Carbonate Leaching Process

Achieve efficient zinc recovery from ores that are not suitable for conventional processing. A significant part of the world's zinc reserves are in the form of zinc carbonate, often containing zinc silicate. Metso Outotec's zinc silicate and carbonate leaching process provides high zinc recovery while still controlling silicon leaching and the removal of silica. After leaching, iron removal and solution purification or zinc solvent extraction steps produce a solution suitable for zinc electrowinning with a final zinc product of SHG ingot.
  • Offers efficient zinc recovery when conventional processing is not sufficient    
  • Manages silicon leaching and silica removal with a specially designed process that gives high zinc recovery levels
