Zinc processing Ores | Britannica

The small fraction of zinc sulfide minerals present in the ore makes beneficiation necessary in order to produce a concentrate suitable for treatment The most common method for accomplishing this concentration is to isolate the sulfide mineral from the impure constituents, or gangue, by flotation separation In this process, the ore initially is crushed to about 19 centimetres (075 inch

The percentage of zinc in the ore mined is frequently very low, and often averages 3 per cent, but this is increased by concentration The Broken Hill district in New South Wales produces about 20 per cent, of the world's production in the form of concentrates, averaging from 40 to 45 per cent, metallic zinc Zinc sulphide oxidizes to the soluble zinc sulphate, and zinc minerals are readily

Sedimentary exhalative deposits Wikipedia

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of orebearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore SedEx deposits are the most important source of lead, zinc and barite, and a major contributor of silver, copper, gold, bismuth and tungsten

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
