    For example, ZnS, Zinc Sulfide or also known as zincblendes is an ore of zinc. Extraction of Iron. Iron is a fairly reactive metal, hence we cannot find iron in its pure form. We have to obtain iron from its ores. Iron has three ores from which we can obtain it from. The three ores of iron are: Pyrite (FeS 2) Magnetite (Fe 3 O 4) Haematite (Fe 2 O 3) Industries usually use Haematite to extract

  • 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. Due to its very low boiling point, at such temperatures, zinc will escape with exhaust gases
