Maximizing the recovery of fine iron ore using magnetic ...

    ore beneficiation is that treatment of –10 µm iron ore is possible – in flotation the feed is deslimed at 10 µm and the –10 µm stream is considered to be final tailings even though there is often a significant amount of contained iron ore. The recovery of fine iron ore by magnetic separation will

    Ore Dilution & Recovery in Mining

    Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall.

    Recovery of Iron Ore Tailings byColumn Flotation

    The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm [1]. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides.

    Recovery of Gold in Pyritic Sulfide Ores

    Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores.
