     • Calcination and Roasting are processes used to convert ore into oxide. The difference between the two is the presence or absence of air. Roasting involves heating ores with oxygen below their melting point in the presence of air. Calcination involves heating ore to a high temperature in the absence of air.

   What is the difference between calcination and roasting?

   • Here are some of the major differences between calcination and roasting. Roasting involves the heating of ore lower than its melting point in the presence of air or oxygen. Calcination involves the thermal decomposition of carbonate ores. Roasting is carried out mostly for sulfide minerals. During calcination, moisture is driven out from an ore.

   What are roasting and calcination methods?

   • Roasting and calcination methods are applicable for the extraction of metals. The ores or minerals containing metals are not always present in the oxide form, in that case, they are subjected to undergoing roasting and calcination processes. Both processes change the ore into their oxide form. This makes the extraction process easier.

   What is roasting in metallurgy?

   • Roasting is a process of metallurgy where ore is converted into its oxide by heating it below its melting point in the presence of excess air. While calcination is mostly used in the oxidation of carbonates, roasting is a method that is used for converting sulphide ores.

   What is an example of calcination?

   • A typical example for calcination is the production of lime from limestone. There, limestone is given a high temperature that is enough to form and release carbon dioxide gas. Lime is produced in an easily powdered condition. Roasting: Roasting is the heating of a metal ore in the presence of excess air or oxygen.
