  • Specifications Of Iron Ore Use In Steel Making

    Specifications of iron ore use in steel making. Copper Ore Crushing Screening Plant. Inside the main crusher, the copper ore is broken into smaller pieces of much less than 25 centimetres. The vibrating feeder is mainly used for continuously and evenly feeding coarse crusher,.Jun 22, 2016 Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal.
