Historic smelter in Florence, Colorado

In extractive metallurgy, a smelter is a factory for producing metal by the reduction of ore. Image File history File links Smelter_FlorenceColorado. ... Image File history File links Smelter_FlorenceColorado. ... Florence is a city located in Fremont County, Colorado, USA. As of the 2000 census, the city had a total population of 3,653. ... Extractive metallurgy is the practice of extracting metal from ore, purifying it, and recycling it. ... A factory worker in 1940s Fort Worth, Texas. ... Hot metal work from a blacksmith In chemistry, a metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. ... Semi-accurate illustration of a redox reaction Redox reactions include all chemical processes in which atoms have their oxidation number (oxidation state) changed. ... Iron ore (Banded iron formation) Manganese ore Lead ore Gold ore An ore is a volume of rock containing components or minerals in a mode of occurrence which renders it valuable for mining. ...


Most smelters use specialised metallurgical furnaces to accomplish this. These are (or were) of various kinds. For iron, the primary smelting took place in a bloomery or in a blast furnace. For base metals such as copper and lead, smelt mills were used and later reverberatory furnaces known as cupolas. A furnace is a device for heating air or any other fluid. ... A bloomery is a type of furnace once widely used for smelting iron from its oxides. ... It has been suggested that Old Furnace, Ironbridge be merged into this article or section. ... In chemistry, the term base metal is used informally to refer to a metal that oxidizes or corrodes relatively easily, and react variably with dilute hydrochloric acid (HCl) to form hydrogen. ... General Name, Symbol, Number copper, Cu, 29 Chemical series transition metals Group, Period, Block 11, 4, d Appearance metallic pinkish red Atomic mass 63. ... General Name, Symbol, Number lead, Pb, 82 Chemical series poor metals Group, Period, Block 14, 6, p Appearance bluish white Atomic mass 207. ... A reverbatory furnace is a metallurgical or process furnace which characteristically isolates the material being processed from contact with the fuel, but not from contact with the combustion gases. ...


Some smelters required a forced draught provided by bellows to blow in air and heat up the interior so that it was hot enough to melt metals. In the industrial revolution, bellows were replaced by blowing tubs (or cylinders), usually operated by a steam engine. However reverberatory furnaces are air furnaces, where the draught was provided by convection as a result of hot gases rising up a chimney. Some have long flue systems, so that the flue gases cooled enough for metal vapour to condense. Hand bellows The bellows is a device for delivering pressured air in a controlled quantity to a controlled location. ... A Watt steam engine in Madrid. ... A reverbatory furnace is a metallurgical or process furnace which characteristically isolates the material being processed from contact with the fuel, but not from contact with the combustion gases. ... Convection is the internal movement of currents within fluids (i. ... A chimney is a system for venting hot gases and smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. ... In the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i. ...
