The principle ores of are hematite 70% and magnetite 72% . Taconite is a low-grade ore, containing up to 30% magnetite and hematite. Type
Gondwana contain nearly 98 per cent of reserves. Gondwana is much younger than the Carboniferous and hence it’s carbon content is low. They have rich deposits of ore, copper, uranium and antimony also. Sandstones, slates …
Mining iron ore or other iron-bearing materials from the ground is the first step to make iron and steel. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite Fe 2 O 3 or magnetite Fe 3 O 4. Common types of iron ores and their iron contents are shown in Table 2.1. Six major countries in iron ore mine production from 2010 to 2013 …
Iron is a which occurs naturally as iron ores from which metallic iron is extracted and is the most commonly used heavy metal. Important ores include magnetite iron II, III oxide—Fe 3 O 4 , hematite iron III oxide—Fe 2 O 3 , limonite a mixture of hydrated iron III oxide-hydroxide in varying compositions FeOOH and goethite FeOOH.

Our Earth is made mostly of . The are composed of mineral grains combined in different ways and having various properties. Minerals are naturally occurring chemical compounds in which atoms are arranged in three-dimensional patterns. The kind of elements and their arrangements lead to a particular appearance and certain properties for each mineral.
