Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Froth flotation is commonly used to separate many types of metals from their ores. In this process, ore is crushed, then soaked in a solution that makes the metal in the ore hydrophobic. Hydrophobic literally means afraid of water. After this occurs, the ore is put in a large vat with soap/detergent and air is flowed through the ore.
