The study of metals and the process for refining and making things from them is called metallurgy. Metallurgy is said to be the scientific study both of the extraction and refining process of metals from their ores. This process includes steps such as grinding of the ore also called ore pulverization. Ore is crushed to increase its surface area for purpose of increasing the level of its reactivity. Sometimes, the ore is heated in the presence of oxygen to turn the ore into and oxide. This process is known as roasting.
