· Non-sulfide zinc ores are an important resource that can be used for the production of zinc. These ores were the prime source of zinc metal production for hundreds of years, but their significance decreased during the early 20th century due to the development of flotation and smelting techniques for zinc sulfides (Schneider et al., 2008).
