Calcination Process
Calcination Process is carried out by heating a chemical compound at a very high temperature without melting it. It is performed under very little supply of oxygen. There are several steps performed during calcination process. These steps are:
- Preparation
- Heating
- Chemical Reaction and
- Cooling
Preparation
The material is crushed and grinded into small particles from large solid ores. These small particles will enhance the efficiency of the calcination process.
Heating
After that, the material is heated to high temperatures in a regulated setting. The material and the intended result determine the precise temperature and heating time. For instance, calcium carbonate is heated to temperatures more than 800 degrees Celsius.
Chemical Reaction
After heating the material the chemical reaction is performed with a limited supply of oxygen. The chemical reaction removes water from the material and yields its oxide. Carbonates and other compounds decompose, lose moisture, and undergo oxidation or reduction when a substance is heated below its melting points at a high temperature.
Cooling
After the desired chemical changes have taken place, the material is allowed to cool down. The cooling process may be slow to avoid undesired reactions or changes.
Calcination
Calcination refers to a thermal treatment process applied to ores and other solid materials in the absence of oxygen or air. Calcination is one of the important methods used for the extraction of metals in metallurgy. This process is carried out in a controlled environment with a regulated temperature. The calcination method generally removes moisture from compounds.
In this article, we are going to discuss the Calcination process, Calcination definition, Calcination formula, Calcination example, the difference between calcination and roasting, and a few applications of calcination.
