Spalling was a common process in ancient times when there was the absence of machinery. In this process, the raw ore was broken up by hammers and wielded by hand. The main motive of ore dressing is to remove unwanted particles such as dust and other minerals, gangue or matrix from the ore.

Mineral processing is the first step for ore once it leaves the mine. The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals from the gangue (low-value) minerals that surround them in order to produce a concentrate made up of useful minerals.
