Discovered in the late 1890s, the mine has produced around 900,000 tonnes of magnetite ore with an estimated grade of 58% iron. Magnum states that the project has an indicated resource of 151 million tonnes (mt) of iron at 19% with a recovery rate of 23.2% and has an inferred resource of 81mt at 18% with a 22% recovery rate.

Heavy Media Separation: Magnetite is used in dense medium separation processes in the mining and mineral processing industries. It is mixed with water to form a dense medium, and its magnetic properties are employed to separate valuable minerals (e.g., coal, copper, gold ) from waste rock in ore beneficiation.

Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of …

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.

Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.
