calcination or roasting of ore

Calcination and roasting Metals such as iron, zinc, lead, copper, etc, are in the middle of the reactivity seri These are moderately reactive metals and are usually present as sulphides or carbonat A metal is obtained from its ore by the processes of reduction or by electrolysis , In calcination, the ore is heated below its melting.

Calcination

The IUPAC defines calcination as "heating to high temperatures in air or oxygen" However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decompositionA calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature.
