What is Iron Ore? Iron ore is a rock from which metallic iron can be economically extracted. Iron is the most used metal accounting for about ninety five per cent of the total metal produced worldwide. It can be alloyed with many elements to produce stronger and harder products which are used in millions of items we use every day.
Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective.

Smelting Reduction. Figure 2: The smelt reduction vessel (SRV) is the core technology component of the Hismelt process. Source: RioTinto While years of ironmaking technology innovations have optimized blast furnace productivity, two alternative processes—smelting reduction and direct iron reduction— are growing in adoption. The …
In the past, a lot of experimental research work on this type of iron ore beneficiation, including reduction roasting – weak magnetic separation process of the selection index is relatively good, but because of its technical difficulties is the need for ultra-fine grinding, and the current conventional beneficiation equipment and chemicals ...
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter …
Iron ore pre-treatment equipment. The pre-treatment stage of iron ore mainly includes crushing, screening, grinding, and grading processes.. Crushing and screening: The raw ore is sent to the crusher by the vibrating feeder, and the crushed product enters the screening machine. The materials on the screening return to the crusher for further crushing, and the …
As an integral component in the formation of steel, iron ore is the world's most commonly used metal and critical to nearly every industry, from energy and construction to transportation and equipment manufacturing. Beyond its applications, iron ore production is an economic stimulant essential to U.S. growth.
