Smelting

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base 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.

Feb 08, 2021 · Procedures for Metal Extraction. Concentration of Ores: Ores may be concentrated either by (i) Washing away the earthy materials in a stream of water in order to leave behind the heavier ores as is the case with tin ore or by (ii) Froth flotation where the ores are churned up with oil and water to form froth. This froth which contains the ore is skimmed off by blowing air.
