The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an …

Until the 1960s, the basic product was high-iron lump. As the supply of lump fell, the first pelletizing plants were set up in Brazil, which allowed the use of fine ore (pellet feed) and continue to be important for the steelmaking chain. The briquette, as well as pellets, are part of Vale's portfolio of high-quality products.
