  • Hematite: The mineral hematite information and pictures

    Hematite is the principle ore of iron. Huge quantities are mined throughout the world for industrial production. It is the source for roughly 90 percent of all iron mined in the United States. Hematite was largely used in the past as a red and brown pigment, although Iron ore Wikipedia,Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.What is the chemical composition of iron ore answers,Iron ore is any rock that contains a usable quantity of iron. Common iron ore minerals include hematite, magnetite, limonite, and siderite. These are frequently found together with assorted silicates.
