Calamine ore can be used to extract one of the following metals.This metal is lakhmir singh manjit kaur - chemistry a metal x which is resistant to corrosion is produced by the electrolysis of its molten oxide whereas another metal y which is also resistant to corrosion is produced by the reduction of its oxide with carbon.
Concentrated ore can be converted into its metal oxide by calcinations or roasting.Calcination is the process of converting an ore into its oxide by heating it strongly below its melting point, either in the absence of air or in a limited supply of air.Roasting is the process of heating an ore in a furnace, with regular supply of air, at a.
A carbonate ore is first converted into oxide ore by calcination.A sulphide ore is converted into oxide ore by roasting.1.Calcination process it is the process of heating the concentrated ore at a temperature not sufficient to melt the ore.The water content and the volatile impurities also get expelled.Zinc carbonate in its ore calamine.
Question 11 i give the name and formula of the ore of zinc containing its sulphide.Ii write equations for the following steps in the extraction of zinc.1 roasting of the ore.2 reduction of the zinc compound which is the product of the above reaction.Or in the process of extracting zinc, the above named ore is roasted.
Zinc - simple english wikipedia, the free encyclopedia.That is why zinc sulfide is the most common zinc ore, not zinc oxide.Chemical compounds.Zinc can make chemical compounds with other elements.These chemical compounds are only in one oxidation state 2.A 1 compound has been found but it is hard to make.Contact supplier.
Jan 20, 2018 answer zinc is extracted by the process of roasting from sulfide ore and from the carbonate ore, the process used is calcination.Explanation zinc is the metal which is present in the middle of the reactivity series.It is found in the ores of its sulfides or carbonates.Contact supplier.
Manufacturing process of zinc sulphate from zinc oxide.A wide variety of zinc sulphate manufacturing process options are available to you, such as agriculture grade, stone grade, and industrial gradeou can also choose from zinc sulphate, sodium hydrosulfite, and copper sulphates well as from free sampleshere are 86 zinc sulphate manufacturing process suppliers, mainly located in asia.
Calamine is a historic name for oxidized zinc ore, derived from the belgian town of kelmis la calamine in french, which was home to an important zinc mine and processing plant.The mineralized protore can be either a mississippi valley-type deposit, or a sedex, or a polymetallic crd.
The reduction of zinc oxide to zinc occurs at a higher temperature than that required for the reduction of copper oxide to copper.Coke is used for the reduction of zinc oxide.Depending on whether sulphide or carbonate ores used for the extraction, the concentrated ore is either roasted or calcined.
Along with this, metal carbonates and hydroxides are converted into its oxide.Roasting it is the process in which the ore is heated in the presence of air at a temperature below its melting point so that the moisture content of ore, sulfur, phosphorous, etc, are converted into its oxide and can be removed.Sulfide ores also get converted into.
