  • Extraction of Zinc Application Of Zinc Refining Process

    The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.

    However, any iron sulfide present in the ore will be converted to iron (III) oxide, which reacts with zinc oxide to form zinc ferrite: In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter.
