Iron ore BHP

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Iron ore raw materials URM-Company

Sinter ore (iron-ore fines) is produced by crushing, screening and deslurrying high-grade ore rich in iron, fineness being less than 10 mm. Direct-shipping ore (lumpy ore) is also produced from high-grade ore, fineness being minus 70 and plus 10 mm. Iron-ore raw materials for a blast-furnace process are usually sintered or pelletized.
