After the ore is extracted, it undergoes crushing and grinding to reduce its size and prepare it for further processing. The ore is crushed into smaller pieces using crushers and then ground into a fine powder using grinding mills. This process increases the surface area of the ore, facilitating chemical reactions in the subsequent steps.
