Plasma exists as the fourth state of matter after solid, liquid, and gas. There are two key classifications of plasma, thermal (equilibrium) and nonthermal (nonequilibrium) plasma. A thermal plasma is generated when a gas is heated at a high-temperature range of about 20 000 K to achieve the ionization of the gas.
Calcination is a thermal treatment process most commonly applied to inorganic products. In its most conventional meaning, the term "calcination" is widely used in industrial thermal processing terminology to describe the processes of burning the lime or converting the iron ores into oxides.

The originally proposed concept included two technology options – 1) a smelting process and 2) a smelting plus vaporization and condensation process. For both options, coal fly ash would be smelted in a plasma arc heated furnace under reducing conditions to separate ash into molten slag and reduced metal (primarily iron) phases.
Thermal plasma technology may be useful for a broad range of applications in extractive and process metallurgy. Plasma technology is being used in the melting/remelting and refining of metals ...

Mineral is defined as a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties. By comparison, a rock is an aggregate of minerals and/or mineraloids and does not have a specific chemical composition.
Plasma, referred to as the "fourth state of matter," is a very high temperature, highly ionized (electrically charged) gas capable of conducting electrical current. Examples of plasma in nature include lightning and gas at the surface of the sun. Plasma technology has a long history of development and has evolved into a valuable tool for ...
