Limonite iron ore. Limonite is a yellowish-brown iron ore and was the most important source of iron for the iron and steel industry in the Lehigh Valley during the 1800s and early 1900s. The abundance of anthracite coal from the northern portion of our area helped fuel the blast furnaces used in the production of iron and steel during this time.

Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.

Limonite - Wikipedia

While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.
