New Method Of Rich Oxidized Zinc Ore Sulfuric Acid Leaching

New Method Of Rich Oxidized Zinc Ore Sulfuric Acid Leaching

May 18, 2020 Shaimerden oxidized zinc ore containing more than 21% wt.% zinc is studied in this work. When the first research on hydrometallurgical processing of this ore was conducted the authors of this research determined the following parameters for ore leaching: the size of ore reduction, sulfuric acid concentration, temperature, and leaching duration. These tests serve as a basis for zinc …

The ore deposit of Skorpion Zinc is unique as it is a primary oxide/silicate/carbonate zinc deposit, which cannot be concentrated by flotation. The absence of sulphur offers an advantage in that no sulphur or sulphuric acid disposal is required. The ore is leached directly in sulphuric acid to produce zinc sulphate.
