Beneficiation by magnetic elimination of iron is practiced on a limited scale, primarily on ore consumed in abrasive and refractory industries. The bauxite is usually dried or calcined before magnetic separation because the heating converts siderite (FeCO 3 ) to magnetite (Fe 3 O 4 ), leaves pyrite (FeS 2 ) as a magnetic residue, and makes ...

Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated.

The solarthermal beneficiation of IO2 entails the higher dry iron ore production relative to IO1 through the entire range of heat supplied. This is attributed to IO2 having a lower level of moisture content, which leads to lower solar energy input for water evaporation per tonne of inlet iron ore as compared to IO1.

In our previous studies, we investigated the performance of a novel pneumatic planar magnetic separator (PMS) for the dry beneficiation of a selected magnetite ore. In the present study, we have extended the studies on the PMS with the focus on investigating how various PMS processing flowsheet configurations influence its performance. The outcomes were subsequently compared with those of a ...

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of ...
