Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

The source of the sulphur in these ore bodies is either from the magma itself or from the pre-existing rock where it was present as sulphate. The most common nickel mineral in these ores is pentlandite, (Ni,Fe) 9 S 8. The atomic ratio of nickel to iron in pentlandite ranges between 0.34 and 2.45. Most often, though, it is about 1.15.

Considering the original sulfur-containing compounds presented in Fig. 3 (a,b), and the equilibrium composition of the sulfur-containing gases of the input gas mixture (Fig. 3 (c)), it is proposed that SO 2 and CO react with each other to form COS and S 2 which subsequently react with iron-containing components in the ore and form iron sulfide.
