Early iron-making efforts made use of the local "brown iron ore" (the mineral limonite) and charcoal at massive stone furnaces such as those at Tannehill (1830), Polkville (1843), Shelby (1844), at Round Mountain (1852). The industry expanded dramatically with the discovery of red ore (hematite) at Red Mountain near Birmingham.

Nickel-rich limonite ores represent the largest reserves of nickel. Such minerals are classified as lateritic nickel ore deposits.. One of the first uses was as a pigment.The yellow form produced yellow ochre for which Cyprus was famous, while the darker forms produced more earthy tones. Roasting the limonite changed it partially to hematite, producing red ochres, burnt umbers and siennas.
