process of smelting iron ore

  • Smelting Cornish Mining World Heritage Site

    How does smelting work? Smelting is the process of extracting a metal (like tin or copper) from its ore. Most ores are a chemical compound of metal with other elements, like or oxygen sulphur. Smelting uses heat and a reducing agent, like coal, to remove these other elements from the metal.

  • Smelting Wikipedia

    Most early processes in Europe and Africa involved smelting iron ore in a bloomery, where the temperature is kept low enough so that the iron does not melt. This produces a spongy mass of iron called a bloom, which then must be consolidated with a hammer to produce wrought iron.

    The process of manufacturing iron advanced with the extraction of iron from the ore. First, the ore was crushed into small pieces, which were then roasted to concentrate the iron content. Thereafter, the roasted ore went into the blast furnace for smelting. This involved introducing a heavy charge of charcoal, together with

    May 20, 2017 Smelting your own iron by digging up ore, clay and sand, and turning them into a bar iron using heat and hard work alone, is a transformative process which carries much mystery and appeal. The whole act of taking what is essentially dirt and transforming it into iron and steel, which can then be turned into

    Jul 8, 2009 Finding ways to process the raw materials on a domestic scale is also an issue. For example, my first attempt to extract metal involved a chimney pot, some hairdryers, a leaf blower, and a methodology from the 15th century — this is about the level of technology we can manage when we're acting alone.

    To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. The carbon combines with oxygen to create carbon dioxide and carbon monoxide (releasing lots of heat in the process). Carbon and

    The process of smelting iron ore—processing the ore in a blast furnace—reverses the reaction. (Figure 97) In the intense heat of the blast furnace, the reaction is coupled to another reaction, the spontaneous reaction of carbon with oxygen: C(s) + O2(g) → CO2(g). These reactions are coupled because the O2 produced by

    Mar 13, 2010 The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron.

    Iron smelting thus can be a "selffluxing" process, meaning you do not have to add flux material as long as the ubiquitous silies from the gangue were around. Early iron smelters indeed did not use flux materials. Selffluxing also means that your smelting efficiency goes down, since quite a bit of your ore ends up in the
