What is tha Difference between Roasting and calcination

Definition of Roasting:

The process of metallurgy is generally known as roasting.Tge heating of air is mainly occupied in this process.The solid gases that are mainly react with solid gas thermal reaction.Thus the pollution is mainly occupied in the roasting.

What is tha Roasting:

1.The sulphide minerals that are carried out by the roasting.

2.The ores are always dehydrating with the roasting.

3.During roasting large amount of toxic , metallic and acidic compounds that are always released by the roasting.

4.Roasting involves in heating the material and low melting point is present in the air oxygen.

5.The melting point is always low.

6.The roasting takes part in the place of reducing agent.

Definition of calcination:

The word calcination is meaning of calcium that is reduced and consider by the molecules.The melting point of air is absence in the current supply.Thermal composition of air is getting reduced by the calcination.

What is tha Calcination:

1.The decomposition of carbonate ores are called as calcination.

2.The minerals are always dehydrating with the calcination.

3.It is derived from the moisture of air.

4.This process will lead to the absence of air.

5.The melting point is always high.

6.This information of calcination is always equal to the high density.
