Magnetic separation of hematite and limonite fines as hydrophobic flocs from iron ores

Innovative methodology for comprehensive utilization of iron ore tailings

“…First of all, the recovery of iron is the first step of the whole technology. The recovery of iron from low-grade iron ore was investigated by many researchers using froth flotation process [13], reverse anionic flotation of quartz [14], and magnetic separation [15]. As we all know, the most economic and environmental friendly method to recover iron is magnetic separation.…”

Slag/Metal Separation from H₂-Reduced High Phosphorus Oolitic Hematite

“…Therefore, it is of great urgency to make full use of the refractory ores. Until now, many technical routes have been proposed for the utilization of high-phosphorus iron ores, including physical separation, 3,4) bio-leaching, 5,6) flotation 7,8) and hydrometallurgical process.…”

Electromagnetic–mechanical desalination: Mathematical modeling

“…Magnetic separation is considered a simple technique in the mining industry for various applications. It has been used for separation of magnetic from nonmagnetic waste, or for separation of gangue from ore to increase the concentration of ore [16,17]. Some research work on magnetic separation has also been used in the waste water treatment [18,19].…”
