Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.
