Iron ore - Vitol. Iron ore is the core component of steel, which is used in many forms of modern construction. Steel can be recycled – on average it takes 17 years for a piece of steel to be reused – so demand is proportionately much higher in countries which are industrialising.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
another study on injection of iron ore fines, it was found that the Si content was decreased. If sinter fines containing CaO were used the effect was higher. When a mixtur e of iron ore and coal fines or a water-slurry containing iron ore was injected, decreased silicon content of the hot metal could be noticed. The injection of iron ore ...
