difference between calcination and roasting

CALCINATION ~ it is the process in which carbonate ore is heated strongly in the absence of air to convert it into metal oxide.

ROASTING ~ it is the process in which sulphide ore is strongly heated in the presence of air to convert it into metal oxide .

 CALCINATION- 1. In calcination, the metal ores are heated in limited air.                                                                                                    2. This process helps in the extraction of metals from carbonate ores.                                                 ROASTING- 1. In roasting, the metal ores are heated in the presence of excess air.                                                                           2. This process helps in the extraction of metals from sulphide ores.

Roasting: It is used to convert sulphide ores into oxides. Roasting involves strong heating of iron ore in the presence of excess air. For example, copper sulphide in copper glance ore is converted into copper (I) oxide by heating it in the presence of oxygen.

Calcination: It is used to convert carbonate ores into oxides. Calcination involves strong heating of the ore in the absence of air. For example, calamine ore, which is chemically zinc carbonate, is converted into zinc oxide by heating it in the absence of air.

1)Calcination is the process of converting carbonate ores into oxides.

2) roasting is done by heating in the prescence of excess air

2)calcination is done by heating in the presence of limited air.

3)eg for roasting- copper sulphide in copper glance ores is converted into copper oxide by heating in the presence of oxygen

3)eg for calcination-calamine ore is converted into zinc oxide by heating in the absence of air.

Calcination→Calcination is the process of converting hydroxide and carbonate ores to oxides by heating the ores either in absence or in a limited supply of air at a temperature below it melting point of the metal. This process causes the escaping of volatile matter leaving behind the metal oxideRoasting→the process of heating concentrated ore below it's melting point in excess of air this is called roasting

Roasting is a pyrochemical process in which the ore is heated in the presence of oxygen or air is below its melting point. ... roasting is done in reverberatory furnace. Ex:-2ZnS+3O2 ----> 2ZnO+SO2. Calcinationis also a pyrochemical process in which ore is heated in the absence of air.the is decomposed in this process.

Alloys are used in electrical heating devices because they have high resistivity and they donot burn at high temperature. This shows that alloys have high melting point.

When sulphide ore are converted into oxide by heating strongly in the precence of excess air. This process is known as roasting
Example of roasting
2ZnS+ 3o2 ------ 2Zno + 2SO2
The carbonate ores are changed into oxide by heating strongly in limited air. This process is known as calcination

Calcination-The strong heating of concentrated ores in the limited amount of air.It is mainly used fir carbonate ores and sometimes oxides ore also hametite.It gives carbondioxide gas

Rosting-The strong heating of concentrated ores in the prence of sufficient air. It is used for sulphide ores.It gives SO2gas

Calcination is done in absence of air(O2).
It is used for separation of metal carbonates to convert to metal oxide and carbon dioxide.



Roasting is done in presence of air(O2).
It is used for sulphide ores mostly to replace the sulphur with O2

(2)Roasting:-the process of refining of metal in the absence of oxygen is known as Roasting........
(3) calcination process is used for sulphide ores and well as carbonate ores...
(4) Roasting process is used for only sulphide ores...
