    Sintering: A Step Between Mining Iron Ore and Steelmaking

    World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

    Vale to invest US$2.5 billion in dry iron ore processing

    Dry processing is linked to the quality of the iron ore extracted from mining. In Carajás, as the iron content is already high (above 64%), the ore is only crushed and sieved, so it can be classified by size (granulometry). In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites. To increase the content, the ore is concentrated by means of wet processing (with

    Iron Ore Statistics and Information USGS

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for
