  • Technology IMC

    The traditional way to reduce iron oxide to iron is through a blast furnace using coking coal as a reductant. The process we intend to apply, called Direct Reduced Iron (DRI), uses natural gas to reduce iron ore pellets to highly metalized pellets of iron metal. After the reduced pellets emerge from the shaft furnace, they are hot and malleable.

  • Pellets Vale

    Pellets are used in the production of steel which is used in the construction of bridges, cars, planes, bicycles, household appliances and more. But, before this, the ore passes through a blast furnace that only works when air can circulate freely. For this reason, the material needs to be big enough so that there are spaces between each piece.
