Apr 14, 2021

Magnetic separation of iron mineral fines as consist of C8 –C10 alkanes through IR spectra. Kerosene hydrophobic flocs was added into ore slurries as oil emulsion, which was After the conditioning, the slurry was fed to a labo- prepared by using an ultrasonic crusher along with so- ratory Jones magnetic separator in 500 ml/min flow rate dium

    Jan 31, 2021 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
