2014-7-28  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 micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.

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 iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3),

The Making of Iron & Steel

2020-8-3  2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).
