Influence of Mineralogy on the Dry Magnetic
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 re In the present investigation, two different types of manganese ore were studied in detail to understand the influence of In this study, ferruginous lowgrade manganese ore was prereduced by CO, which converted iron oxide to Fe3O4 while manganese oxide was reduced to MnO Then, the ironrich component was collected by magnetic separation The effects of sample particle size and various other reduction parameters on the efficiency of magnetic separation were studiedPrereduction and magnetic separation of low grade The utilization of lowgrade manganese ores has become necessary due to the intensive mining of highgrade ores for a long time In this study, calcined ferruginous lowgrade manganese ore was selectively reduced by CO, which converted hematite to magnetite, while manganese oxide was reduced to MnO The ironrich component was then separated by magnetic separationUpgrading of LowGrade Manganese Ore by Selective

Prereduction and magnetic separation of low grade
In this study, ferruginous lowgrade manganese ore was prereduced by CO, which converted iron oxide to Fe3O4 while manganese oxide was reduced to MnO Then, the ironrich component was collected by magnetic separation The effects of sample particle size and various other reduction parameters on the efficiency of magnetic separation were studiedmetallic Fe The latter two are strongly magnetic, while the manganese oxides are weakly magnetic or nonmagnetic Therefore, the ferruginous lowgrade manganese ore may be upgraded by selective reduction and magnetic separation For the upgrading of ferruginous lowgrade manganese ore by magnetic separation, several studies2–4) on selectiveRetraction: Gaseous Prereduction for the Magnetic The ore enrichment process is designed to increase its manganese content to just over 50% through magnetic separation Part of the enriched ore is directly sold, while another part goes through a pelletizing process in which the mineral is mixed with coke and exposed to high temperatures, which increases its manganese content to around 56%Comilog, the world's number 2 producer of high
