Three potential sources (from the ores sinter or scrap) of naturally occurring radionuclides in the slag are discussed. Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for ironmaking iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper 2005).

· Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micropore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.
· The StepbyStep Process of Producing Iron from Iron Ore. Some years ago the ancient Egyptians derived iron from the fallen meteorites (or so they say) carved them and made tools and equipment besides jewelry. We have come a long way since then. Now first of all pure iron is rarely available (except if one or two meteorites crash).

· iron processingiron processingIron making The primary objective of iron making is to release iron from chemical combination with oxygen and since the blast furnace is much the most efficient process it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries but less than 5 percent of iron is made this way.
History of Metal Processing. Iron s beginnings date back many centuries. The first recorded use of iron was in 1800 BC by a people known as the Chalybes. The Chalybes wanted to make unparalleled weapons. At the time bronze was primarily used but it wasn t ideal as it was softer than iron. So the Chalybes would put iron ore into a hearth

· Many iron ore producers are facing challenging times processing crude material with rising levels of impurities and a volatile iron ore price. Beneficiation particularly washing (scrubbing) can be the key to upgrading the ore to earn more per shipped tonne. Highend steel production at a low coke consumption level and a high productivity rate can only be achieved by using highquality
· When the iron ore is extracted from the mine it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
