Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. Mineral deposits can be classified as: Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction.; Mineral reserves or Ore reserves are valuable and legally, economically, and technically ...

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Except for iron ore and bauxite our share of world reserves of every other mineral is one percent or less. However, there has been a phenomenal growth in production since independence. As per estimates if the present trend of production continues, we will exhaust our reserves of all the important minerals and fuels, except coal, iron ore, limestone and bauxite, in 25 to 30 years.

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
