  • Modern Air Pollution Control For Iron Ore Induration

    Mining and Ore Processing Mercury Pollution. Estimated Population at Risk 1.5 Million. Description. Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large.Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92 94 iron and 3 5 carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various.
