Jan 30 32 Jet Fuel VS Diesel VS Gasoline how they burn and what color are they Duration 14 15 Just Think 4 625 579 views61 Process Overview 611 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface Lead and zinc ore is mined almost exclusively in underground operations though a few surface operations do exist

The major types of zinc ore deposits are generally found to be sediment hosted volcanic hosted intrusion related Broken Ore type or Mississippi Valley Type The Zinc Mining Process The zinc mining process is conducted primarily underground with more than 80 percent of all zinc importer of refined zinc Zinc ores typically may contain from 3 to 11 percent zinc along with cadmium copper lead silver and iron Beneficiation or the concentration of the zinc in the recovered ore is accomplished at or near the mine by crushing grinding and flotation process Once concentrated the zinc ore is

Lead Zinc Ore Processing Lead and zinc is human activity from lead zinc deposit produced earlier one of the metal Lead and zinc are widely used in the electrical industry mechanical industry military industry metallurgical industry chemical industry light industry and The process is carried out in a series of tanks As the lead and zinc minerals are less readily wetted than the gangue they adhere to the air bubbles which are carried to the surface The rock particles sink and the lead and zinc ores are skimmed off Then the lead ore is separated from the zinc ore

Extraction process of Zinc The important ore of Zinc is Zinc blende ZnS So it is extracted from zinc blende by carbon reduction process The following are the steps involved for the extraction process of zinc a Crushing and Pulverization The big lumps of ore is first crushed by a jaw crusher and powered in ball mills b Concentration At the end of the flotation process the lead has been separated from the rock and other minerals too such as zinc and copper have been separated out Filtering 4 After the ore is concentrated in the flotation cells it flows to a filter which removes up to 90 of the water

How are metals extracted from mineral ores How do we make iron steel other alloys aluminium sodium copper zinc titanium and chromium The six linked pages include an introduction to metal extraction or metal manufacture and production There are detailed notes on the extraction of iron and its conversion to steel The extraction and manufacture of aluminium and sodium are describedHowever any iron sulfide present in the ore will be converted to iron III oxide which reacts with zinc oxide to form zinc ferrite In the simple leaching process this zinc cannot be easily recovered and so ores with low iron content are preferable The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter

Zinc can be electroplated on iron by keeping iron article as cathode zinc as anode and znso4 solution as electrolyte On passing current a layer of zinc is coated on iron article b By metallizing Zinc can be directly applied by dipping iron article in molten zinc this process is The process of extracting pure metal from its ore is known as metallurgy Since the nature of the ore and also the properties of different metals are different therefore it is not possible to have the universal scheme which may be applicable to all the metals

The first step in processing zinc metal from its ore ZnS is to react it with O 2 gas according to the reaction below If 620 kg of ZnS is to be reacted what volume of oxygen at atm and 340degreeC is needed at a minimum to carry out this reaction 2 ZnS s Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday useThe most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
