Answer the following questions briefly
1.Write the definitions of *Comminution and *Calcination

Comminution is defined as the reduction of solid materials from one average particle size to a smaller average particle size through various methods which include crushing, grinding, cutting, vibrating etc,

Calcination is also defined as 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(heat) decomposition.

answer:

ask me the quest
