Breaking down the ore proper is more difficult, however, as it is a chemical compound of carbonates, hydrates, oxides, silicates, sulfides and various impurities. To get to the bits of iron in the ore, you have to smelt it out. The chemical composition of direct-ship and beneficiated iron ores can be divided into high-grade hematite ores, with 62–65% Fe and low SiO 2 and Al 2 O 3, largely from Iron Ore - an overview ScienceDirect Topics
