Refiners and Smelters of PGMs (Platinum Group Metals)
Smelting is a process of applying heat to an ore, 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 … See more Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a See more The ores of base metals are often sulfides. In recent centuries, reverberatory furnaces have been used to keep the charge being smelted separately from the fuel. Traditionally, they … See more • Cast iron • Ellingham diagram, useful in predicting the conditions under which an ore reduces to its metal • Copper extraction techniques • Clinker See more Of the seven metals known in antiquity, only gold occurs regularly in its native form in the natural environment.
