Different Types of Iron Ore - Mineral Processing & MetallurgyWhile 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...
