  • Challenges of Removing Fine Iron from Powders

    For fine iron removal the magnetic plates would use high strength neodymium magnets. This magnetic field is further enhanced when a tapered step is added to the face of the magnet. Captured iron migrates behind the step and away from the material flow reducing the risk of re-entering the cleansed product.

  • Fine Gold Recovery. Separating Placer Gold Particles from

    Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget the vast majority of gold that we find as prospectors is very small in size ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from

  • Recovery of Gold in Pyritic Sulfide OresMine Engineer

    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.

    Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey bright yellow deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4) hematite (Fe 2 O 3) goethite (FeO(OH)) limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).
