Electrowinning And Smelting

Zinc Leaching and Purification-Zinc-

The leaching acidity, temperature and pressure are regulated to achieve the most optimal zinc leaching rate. The pregnant leaching solution (PLS) has to be thickened and filtrated to remove leaching residue and purified to get qualified zinc electrolyte. Zinc cathode is produced through electrowinning and then molten and cast into standard ingot.
