01/04/2000  Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the Limestoney silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy to work, making it perfect for creating tools.

The process of iron making is the reduction of iron oxide to iron. Most of the world's iron is made in blast-furnaces, which produce liquid iron. Iron oxides normally occur as iron ores which also contain quantities of impurities particularly silica. Thus, the commercial iron making process involves the removal of these impurities, usually by forming a slag with quicklime.

US4405588A - Process of removing iron impurities from ores ...

A process of removing iron impurities from ores, particularly useful for removing stains of iron impurities adhered to silica sand particles, comprises grinding the ore, washing and desliming the ground ore to remove the major part of the clay-type binder, attrition-scrubbing the deslimed particles to release further amounts of binder therefrom, washing and desliming to remove said binder ...

Iron Ore - an overview ScienceDirect Topics

R. Stace, in Iron Ore, 2015 Abstract. Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective. This chapter will look at case studies that define ...

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen ...

Iron - Essential Chemical Industry

The blast furnace uses either high-grade iron ore or the iron ore pellets together with coke and limestone. In a modern blast furnace, the mass of each component and the timing of its addition to the furnace are computer-controlled, responding automatically to the conditions prevailing at that time in the furnace. The components are added in small amounts every 10-15 minutes at the top of the ...

Impurities Of Iron Ore

Iron ore - Wikipedia. Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue ...
