Currently magnetite iron ore is mined in Minnesota and Michigan in the U.S. and Eastern Canada mine taconite. Magnetite bearing banded iron formation is currently mined extensively in Brazil which exports significant quantities to Asia and there is a large and developing magnetite iron ore industry in Australia.

Within gold ores the element occurs in nature chiefly as native gold which is by far the most common gold bearing mineral. In various gold ores the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold but it also serves as a reducing agent.

Iron ore can be defined on the basis of its iron content into lowgrade ore taconite which commonly contains 25 to 35 iron and highgrade ore which contains 50 to 70 iron. Ironbearing ore minerals include oxides carbonates silicates and in some cases sulfides.

In JSW Steel Limited iron ore is being beneficiated to meet the quality requirement for iron making units. JSW Steel Limited is 10 Mtpa integrated steel plant and requires nearly 25 Mtpa iron ore to produce a ton of steel. In India BellaryHospet region is endowed with large reserves of good quality of iron ore.
The experimental results revealed that the arsenic in arsenopyritebearing iron ore can be removed in the form of As2O3g in an air or nitrogen atmosphere by a roasting method. The efficiency of arsenic removal through roasting in air was found to be less than that in nitrogen atmosphere.

Iron processing Iron processing Ores Iron ores occur in igneous metamorphic transformed or sedimentary rocks in a variety of geologic environments. Most are sedimentary but many have been changed by weathering and so their precise origin is difficult to determine. The most widely distributed ironbearing minerals are oxides and iron ores consist mainly of hematite Fe2O3 which is.

Banded iron formations are predominantly Precambrian in age most are 1.8 to 2.2 billion years old none are younger than Cambrian age. The most important ironbearing minerals in iron formations are hematite magnetite and greenalite. These deposits constitute the worlds major source of iron ore.

In most cases arsenic is an unfavorable element in metallurgical processes. The mechanism of arsenic removal was investigated through roasting experiments performed on arsenopyritebearing iron ore. Thermodynamic calculation of arsenic recovery was carried out by FactSage 7.0 software ThermfactCRCT Montreal Canada GTTTechnologies Ahern Germany.
