Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable. Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.
Calcination is a process of heating a substance under controlled temperature and in a controlled environment. This process is known to improve the chroma, tinctorial strength, pigmentary texture, weather stability, light-fastness and thermal stability of pigment whereas it has adverse effect on the dispersibility of pigments.
Calcination. Calcinations is the process of subjecting a substance to the action of heat, but without fusion, for the purpose of causing some change in its physical or chemical constitution. The objects of calcination are usually: (1) to drive off water, present as absorbed moisture, ...
Calcination. Calcination is a process of heating a substance under controlled temperature and in a controlled environment. From: Handbook of Textile and Industrial Dyeing, 2011 Related terms: Al2O3
Chemically, the Calcination process involves heating a substance in a crucible or over an open flame until it is reduced to ashes. In the Arcanum Experiment, Calcination is represented by sulfuric acid, which the alchemists made from a naturally occurring substance called Vitriol. Sulfuric acid is a powerful corrosive that eats away flesh and reacts […]
Calcination is the process of heating a material to cause chemical dissociation (separation).. Calcination is a common process, and is often used in the creation of inorganic materials, such as the dissociation of calcium carbonate to create calcium oxide and carbon dioxide.
Calcination can also be described as a thermal process that is used to convert ores and other solid materials by bringing about a thermal decomposition. In calcination, the reaction most of the time occurs at or above the thermal decomposition temperature. Calcination is derived from a Latin word calculate which translates as “to burn lime”.
30-09-2015· *Note: The term “calcination” is often loosely used to refer to thermal treatment techniques that may or may not meet the technical definition. Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type.
The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
Calcination: It is a process in which the ore is heated to a high temperature below the melting point of metal in absence of air or limited supply of air. The change that takes place during calcination with reactions are: ∙ Moisture and water from hydrated ores, volatile impurities and organic matter are removed. ∙ Ore becomes porous.
Calcination definition is - the act or process of calcining : the state of being calcined.

Calcination (also referred to as calcining) is a thermal treatment process, in presence of air or oxygen, applied to ores and other solid materials to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The calcination process normally takes place at temperatures below the melting point of the product materials

CHEM GUIDE Calcination and roasting. This process is known as roasting Calcination In this process the ore is heated to a high temperature in the absence of air or where air does not take part in the reaction Usually carbonate ores or ores containing water are calcined to drive out carbonate and moisture impuriti The differences between roasting and calcination are given

Calcination is the process in which the ore is heated below its melting point, either in the absence or in a limited supply of air, in an aim to drive off volatile expunges, moisture, water of hydrates and organic matter from the ore.
A calcination process is often followed by other processes such as sintering, phase transformation or crystal growth. These processes normally require higher temperatures and the product should also not normally be recirculated. Rotary kilns are thus usually no longer suitable for such process combinations.
