    Extraction of Zinc Application Of Zinc Refining Process

    byjus/chemistry/zinc extraction metallurgy

    Zinc Mining. 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.

    Lead and Zinc

    Forms of Lead and Zinc Ore The two principal minerals containing lead and zinc are galena and sphalerite. These two minerals are frequently found together along with other sulfide minerals, but one or the other may be predominant. Galena may contain small amounts of impurities including the precious

    1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide [2]. Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either a metal oxide or a metal itself [3].

    Aug 05, 2016· The first process in the extraction of zinc is the concentration. As shown in the diagram below, this process involves the implementation of froth floatation method for the extraction of zinc ores from zinc blende. Zinc blende is mixed up in a large tank consisting of a mixture of pine oil and water.

    Lead Materials Ore Extraction


    Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi step process.
