    The zinc blende (sphalerite: zinc sulphide)is first crushed to powder and then treated by froth flotation (that process is described in the copper unit. It is used in the extraction of several metals). Tjhe resulting material is known as 'concentrate'. It contains at least 50% zinc Stage 2 Sintering The next stage involves heating the concentrate in air. The sulphur oxidises toproduce sulphur dioxide and the zinc

  • 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.

  • Extraction purification lead zinc titanium chromium

    Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate). (1) The zinc sulphide ore is roasted in air to give impure zinc oxide and forming the nasty poisonous gas sulfur dioxide (sulphur dioxide) .

  • Zinc smelting Wikipedia

    Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.
