WebApr 25, 2024 · The most used processes to smelt copper are reverberation and oxygen flash smelting. For both processes, the resultant molten copper is again processed to achieve the purest copper. 2. Human Health Risks . Continued exposure of airborne pollutants generated by metal processing and smelting has been known to cause chronic diseases. 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.
