Mauritanian iron ore powder (OM) has advantages of high iron grade, low aluminum content, and low loss on ignition, which can be used as a new mineral to replace low alumina limonite that has been exhausted in Australia. However, it will have a certain negative impact on sintering because of its high SiO2 content. The mechanism of SiO2 content affecting the sintering behavior was first studied ...

Ore blending is an essential part of daily work in the concentrator. Qualified ore dressing products can make the ore dressing more smoothly. The existing ore blending modeling usually only considers the quality of ore blending products and ignores the effect of ore blending on ore dressing. This research proposes an ore blending modeling method based on the quality of the beneficiation ...

These steps vary with the respective raw material—for example, ore processing consists of crushing and grinding. For bulk material ( iron ore) once reconditioned, the product is stacked in stockyards and then it is transported to the port.
