Earlier work with iron ore and iron ore fine/slime indi-cates that beneficiation of iron ore and fine/slime containing very low iron and high alumina and silica is quite difficult. Also, it is equally difficult to know the characteristic proper-ties of the particles where most of the population is below 50 micron.

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.
