Magnetite: South Australia's potential | Energy & Mining

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.

Dry beneficiation of iron ore

The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.

On the Mechanisms of Silica (SiO2) Recovery in Magnetite Ore …

Magnetite (Fe 3 O 4) ore is concentrated by low-magnetic-field drums to recover a magnetite concentrate that is low in silica (SiO 2).The presence of SiO 2 in the magnetite concentrate for steel production increases the steel processing costs, so a major challenge in magnetic concentration is to lower the SiO 2 grade in the Fe …

Theoretical Modeling and Experimental Evaluation of …

Recovering vanadium from vanadium titanium-magnetite (VTM) ore using (NH 4) 2 C 2 O 4 is a clean hydrometallurgical process, but the drawback is the low recovery and slow kinetics due to the formation of inhibitor. A novel energy-efficient mathematical model was derived for green leaching of VTM in which the mechanical …
