The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.

marily by cold working. In this case, it is important that the metal not soften appreciably when placed in service. Cold-worked materials with highly distorted microstructures are in a high-energy state and are thermodynamically unstable. Annealing is the heat treatment process that softens a metal that has been hardened by cold working.
