For instance, in the extraction of zinc from zinc blende ZnS, the sulphide is first converted to the oxide by roasting and the resultant oxide is then heated with coke and releases the electrons neededfor the reduction of the zinc ions. READ MORE: The History Of Iron and Steel Production Some metals are obtained by heating their ores in air.
Zinc blende is concentrated by floath floatation process. The pulverized ore is kept in large tank containing water and pine oil. The mixture is agitated bypressed air. Ore forms frothes to the surface while impurities are left in water.

Extraction of Zinc . Zinc blende is concentrated by floath floatation process. The pulverized ore is kept in large tank containing water and pine oil. The mixture is agitated bypressed air. Ore forms frothes to the surface while impurities are left in water. Zinc Blende does not contain a very high percentage of zinc and hence it needs to be concentrated. The best
Extraction of zinc Zinc mostly occurs as sulfide ores, which are heated in air to convert them to zinc oxide. Molten zinc can then be made from zinc oxide by heating with carbon: zinc oxide +
Polymetallic sulfide gold ores containing lead, zinc and copper Polymetallic sulfide gold ores containing lead, zinc, and copper refer to ores that coexist with gold ores and considerable amounts of copper, lead, zinc, and other sulfur ores. The secondary ore hasponents that can be extracted.
Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal orpounds for use in various products.. Zinc Zn is a metallic element of hexagonal close packed hcp crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.

Occurrence and Extraction of Metals MODULE 6 Notes Chemistry of Elements Metals and their alloys are extensively used in our day to day life. They are used for making machines, railways, motor vehicles, bridges, buildings, agricultural tools, aircrafts, ships etc. Therefore, production of a variety of metals in large quantities is necessary for the economic growth of a country. Only a few
Ore Concentration The lead rich ore, with a typical concentration product of zinc, copper and silver production making the extraction of lead more economic than if it occurred in isolation. Ore Concentration The lead rich ore, with a typical concentration range of 3 8 lead, must first be separated from other material the gangue.

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usuallypound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more
