DRI is produced via a process called direct reduction (DR), one of the two main types of alternative ironmaking processes commercially available. The DR process involves the production of solid iron, DRI or sponge iron, from iron ore and a reducing agent (e.g., natural gas and noncoking coal).

The magnetite beneficiation process The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands.

Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but it often has much higher …

The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
