The iron oxides in the ore are chemically reduced to molten iron by carbon and carbon monoxide from the coke. The slag formed consists of the limestone flux, ash from the coke, and substances formed by the reaction of impurities in the ore with the flux; it floats in a molten state on the top of the molten iron.

Dec 29, 20120183;32;Pig iron is the intermediate product of smelting iron ore with a high carbon fuel such as coke, usually with limestone as a flux. Charcoal and anthracite have also been used as fuel.
This investigation of the Eagle Mountain Mine area, though cursory, revealed new structural, alteration, and stratigraphic relations. Eagle Mountain ores were previously an important source of iron to the western U. S. Ore (where fresh) is magnetite pyrite rock forming two stratabound horizons virtually continuous for 11 km.

This flux thinner will help you get all the gold out of your black sands or ore if thats what your smelting. If your just melting Gold or Silver with Borax or Flux and need it thinner to pour this is the mix for you. If you just want to add it right into your flux a good place to start is a 3 Part Flux amp; 1 Part thinner or even 1/2 part thinner.
This corresponds to 1.8kg flux per kg Fe in the ferric state, and 2.3kg flux per kg Fe in magnetite [the usual calcined product], and 2.7 kg flux per kg Fe in the ferrous state [haematite] Further quantities of this flux are added to remove base metals such as Cu and Ni from dore.
The iron ore trade will also be helped by Premier Li Keqiangs various economic stimuli measures. The most significant is a reduction in taxes. The 16% VAT levied on domestic manufacturers and small and micro enterprises will be cut to 13%, and the 10% rate paid by businesses in the transport and construction sectors will fall to 9%.

Hot Briquetted Iron (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces. Aging A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation.
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.

Dec 28, 20130183;32;The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ore, limestone, olivine, bentonite, dolomite and miscellaneous iron bearing materials in the range of 1250 deg C to 1350 deg C. Iron ore pellets are normally produced in two types of grades namely DRI grade and BF grade.
The soft ore is very rich, carrying 45 to 50 per cent of iron. The hard ore is fossiliferous, high in lime, and lean in iron. The iron ranges from 25 to 36 per cent, the silica from 3.5 to 6 per cent, the alumina from 3 to 4 per cent, and the lime from 22 to 25 per cent.
Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition. The powdery material is therefore usually processed into larger pieces. The raw materials properties determine the technique that is used by mills. Sinter. Baked particles that stick together in roughly one inch chunks.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron content.
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite. In soldering, a flux is used to remove oxide films, promote wetting, and prevent reoxidation of the surfaces during heating. Rosin is widely used as a noncorrosive flux in soldering electronic equipment;

Dec 28, 20130183;32;BF grade, DRI grade, flux, pellets, swelling, Iron ore pellets. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal.
Sep 15, 20100183;32;There is no information available on the use of pyroxenite as flux in pelletizing and its effect during induration of iron ore pellets made from alumina rich Indian hematite ores. In this study, the effect of pyroxenite addition on the melt formation and microstructure during the
Limestone is the usual flux for this purpose. It removes the impurities as slag. Beyond this, each metal has its own special methods. Producing iron from its ore is done in a blast furnace. Producing zinc or aluminium from their ores requires (in addition to heat) electrolysis. Iron is smelted from iron ore in large reactors called blast furnaces. A blast furnace is a tall vertical structure which is fed with coke, iron ore
