Ore Grinding Magnetite

effect of additives on grinding of magnetite,aug 01, 1991 investigations have been carried out to evolve a grinding aid useful in grinding a 40 iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture.these investigations established that an addition of 200 g of cao per metric ton of ore was the most effective in grinding quartz.hydrogen reduction of hematite ore fines to magnetite,surplus coke oven gases (cogs) and low grade hematite ores are abundant in shanxi, china. our group proposes a new process that could simultaneously enrich ch 4 from cog and produce separated magnetite from low grade hematite. in this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring.
