Smelting - temperaturedetectors

Smelting involves more than just"melting the metal out of its ore". Smelting is a form of extractive metallurgy; its main use is to produce a metal from its ore. This includes iron extraction from iron ore, and copper extraction and other base metals from their ores.Extraction Of Copper | Mining, Concentration, Smelting,,Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent. (Click here for extraction process) . Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3 )smelting | Definition & Facts | Britannica,In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out at the bottom. A second heat treatment, in another (converter) furnace, is necessary to remove the iron from the matte.
