Studying on Leaching Zinc Oxide Ore in the System of H₂SO₄

Abstract:

Leaching test on the Oxidized Zinc Ore coming from Yunnan Province is studied in the H₂SO₄ system;Systematic studies are made to show the effects of various factors on the leaching rate of zinc. The optimum conditions for leaching is finally confirmed, namely the grinding size is 75% of-0.074mm, concentration of sulfuric acid 15%, temperature 60°C, solid to liquid ratio 3:1, and leaching time 2.5h. Ultimately, the leaching rate of Zn could reach more than 59%.
