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 is an important step in the manufacture of cadmium

Calcination: Calcination is a heating process to remove the chemically combined water from alumina hydrate. The hydrate is filtered and washed to rinse away impurities and remove moisture. The calcining kiln is brick-lined inside and gas-fired to a temperature of 1,100C. It slowly rotates and is mounted on a tilted foundation which allows the alumina to move slowly through it to cooling

Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron, and grain hardness and toughness. Its thermal stability, high mechanical strength and resistance to molten slags make Calcined

Calcination: Roasting: Calcination is the process in which the ore of the metal is heated to high temperature in the absence or limited supply of air or oxygen. Roasting is the process in which the ore is heated to high temperatures in the presence of excess supply of air or oxygen. Calcination consists of thermal decomposition of calcium ores.
