The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron. These ore parts are usually contained in a charge as products of a hightemperature treatment as agglomerate or pellets. Agglomerate currently comprises about 70 % of a metalbearing charge, pellets about 30 %.
Corex Process for Production of Iron. During the late twentieth century, several new initiatives have been taken for the development of the smelting reduction technology which can become alternative route for the production of liquid iron (hot metal) since the conventional blast furnace (BF) ironmaking depends on metallurgical coal, which is required for producing BF coke needed for the ...

Material adapted from: Hudson,, Fox,, and Plumlee, 1999. ... As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of ...
Lime also has important uses in secondary refining of steel and in the manufacture of steel products. Electric Arc Furnaces. In electric arc furnaces, scrap iron and steel, scrap substitutes such as DRI and HBI, pig iron, iron ore, and beneficiated iron ore are placed in a furnace and melted by the use of heat from an electric current.
In Iron Ores Industry, manufacturing process capability is an important factor for business continuity. There are some problems faced in manufacturing process that caused inability to fulfill the manufacturing quantity target.
Iron ore often has silicon dioxide (sand) impurity which must be removed during the process. ... It is solidified by cooling and used for manufacture of building materials (brieze blocks). Reduction of metal ores chemistry. The process of removal of elements combined with metals to obtain the pure metal is called reduction. The element ...
