Magnetite Range Mid West Magnetite Project, Mid Western Locality is a hive of activity for Iron Ore (>40%). Opportunity for recovery of magnetite at coarser grind size of >45 microns 5.4 kWh /t ;14.4 kWh / t .
The target grind size of the circuit varies between the 90-95 percent minus 500 mesh (32 μm) depending on the ore and operating conditions (Rajala et al., 2007). For this specific case, Figure 2 shows the liberation curve for the magnetite ore.
AB - A new pig-iron making process using magnetite ore pellets containing coal as reducing agent has been investigated. The pellets were heated rapidly in argon at furnace temperatures between 1573 and 1723 K and the temperature and partial pressure of …
An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
