taining various combinations of low grade manganese ore fines, mill scale, precipitator dust, recycled slag, and fine fluorspar have been used as an addition to the steelmaking process to form a fluid slag. Some flux materials are added to repair smelting and refining vessel refractory linings. The selection of the flux to be added
· As the majority of Cr rich Indian chromite ore are friable in nature and available in fine form, utilisation of chromite fines for production of superior quality ferrochrome is essential. For this purpose, in the present study, the smelting of chromite pellets, briquettes, sinter and lump ore has been carried out in an electric arc furnace of 50 kVA.
Producing high quality pellets from materials such as iron ore concentrate and chrome at the mine or at a smelter. Industrial Mills : Pelletising waste fines at industrial plants, turning waste streams at the furnace into valuable feedstock.
Direct alloying is the process in which all of the elements needed for alloying can be reduced from their oxides in a furnace or a ladle. This process is one way of reducing the amounts of energy and materials, reducing the loss of alloying elements, and improving working condition. Mill scale produced in rolling mills is considered a rich iron source (> 67% Fe) with minimum impurities.

· Chrome Ores on Ferrochrome Smelting. 201724 Abstract—Chrome ores from six loions across the Bushveld Igneous Complex in South Africa are used to investigate the effects of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity.
Smelting Furnace of Iron Ore Laboratoryscale experiments showed that pig irons and steels of acceptable grade can be made by arcfurnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, the minimum limited only by .

When the powder ore is used alone, it is easy to cause the sintering of the fine ore, which deteriorates the gas permeability of the material surface and seriously destroys the smelting gas. Atmosphere; the use of chrome ore with a large block size tends to increase the thickness of the refining layer, resulting in a low carbon content of the alloy.

low cost smelting chrome ore. Nov 25, 1980 The advantage of agglomerating the fine chrome ore consists in the fact that the fine ore can be smelted industrially But it must not be overlooked that the agglomeration of the fine chrome ore causes considerable expense and also only allows the smelting of ferrochrome alloys containing 65 to 8% by weight of carbon.
