  • STRATEGIES FOR PROCESSING LOWGRADE IRON ORE MINERALS

    For example, many ores contain iron oxide in a nonmagnetic form and are so finegrained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue. Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are required for conventional ironmaking.

  • Estimating the lump to fines composition split in iron ore

    Iron ore is mined, crushed and separated into lump and fines components, which are sold as separate products. Quality (and therefore value) depends upon the shipped composition of each product matching a target composition vector, in iron and in several other minerals. Each day, ore is selected for mining to meet these target grades.
