IRON ORE
As per the Survey conducted by the Indian Bureau of Mines (IBM) in April, 1995. India had 10,053 Million tonnes of Recoverable reserves of Heamatites and 3,408 Million Tonnes of Magnetite. While Zone 'A' comprising of Bihar & Orissa is the largest Heamatite Ore bearing Zone in the Country with reserves of 5951 Million Tonnes consisting mainly of Medium Grade & Low Grade Ore (Iron content 65% and below), Madhya pradesh has the largest quantity of High Grade Ore reserves (Iron content greater than 65%) in the country at 570 Million Tonnes. Karnataka has the highest reserves of Magnetite at 2784 Million tonnes followed by Andhra Pradesh and Goa.

Export
Keeping in view the limited reserve of Chromite ore in the country, only certain grades of ore are allowed for export. Exphasis has been laid on export of beneficiated chromite concentrates. From the year 1997-98, a five year Export policy was decided upon by Government so us to enable the exporters to establish their presence in the international market.

Ferro Alloys
Introduction
Ferro alloys are essential additives in steel making used for imparting desired properties to steel. The product mix of ferro alloy industry mainly consists of Ferro Manganese (Fe Mn), Ferro Silicon (Fe Si.) and Ferro Chrome (Fe Cr.) - called the Bulk ferro alloys. There is another category of ferro alloys, called Noble ferro alloys, which consists of Ferro Vanadium, Ferro Titanium, Ferro Molybdenum, Ferro Niobium, Ferro Tungstun etc., whose production is negligible.
The production of ferro alloys in India started in early fifties with the industry growing manifold during these four decades. The industry is mainly concentrated in four states viz. Orissa, Maharashtra, Andhra Pradesh and Karnataka for their being rich in the basic raw materials for the production of the ferro alloys.
Installed Capacity and Utilisation
There are 35 large and medium size units (including four 100% EOUs) with an installed capacity of 1.3 million tonnes (including 2 lakh tonnes of Charge Chrome capacity of four 100% EOUs). Besides this, there are small scale units having an installed capacity of about 1.80 lakh tonnes per annum.
Ferro alloy industry is a highly power intensive industry. High power tariffs, coupled with relatively poor quality of supply is one of the major reasons affecting the production and profitability of ferro alloy industry. Average consumption of power per tonne of different bulk ferro alloy ranges between 2700-4065 kwh in the case of ferro silicon. Due to this, the capacity utilisation in the industries has been in the vicinity of 50% to 55%. The production of ferro alloys indirectly related to the plan of production and growth of steel industry. The production of major bulk ferro alloys and Noble ferro alloys during last five years was as under:

Coal
Coal is a major raw material for the Iron & Steel Industry which consumes both Coking & Non-Coking coal.
Consumption of Coking Coal
During 1997-98 the consumption of coking coal in SAIL Steel Plants (including IISCO), TISCO and VSP was as under :

Consumption of Non-Coking Coal
During the year 1997-98 SAIL Steel Plants (including IISCO) consumed 4.562 million tonnes of non-coking coal from domestic sources which TISCO consumed 1.450 million tonnes of non-coking coal. During 1997-98, VSP consumed 1.39 million tonnes of non-coking coal.
Refractories
Refractories are the primary materials used in the internal lining of industrial furnaces and are classified from the chemical composition angle into - Acid Refractories, Basic Refractories and Neutral Refractories. In steel industry refractories are used for lining of coke oven batteries, blast furnaces, steel production furnaces, reheating furnaces, electrical arc furnaces etc. With the technological changes in the steel industry, the major thrust has been on economising on the use of the materials and improving technology in each area of operation/process where refractories are being used. The gradual phasing out of open hearth furnaces, adoption of continuous casting route and modernisation of secondary steel making processes, have lessened the demand for conventional refractories and increased demand for high performance refractories. In general, it can be said that all these improvements have resulted in lowering specific consumption of refractories per tonne of steel.
