Methods Of Beneficiation Of Iron Ore 1

There are many kinds of iron ores in the nature, so the iron beneficiation methods also vary. According to the iron ore features, different iron extraction processes used to deal with different iron ores can obtain the best mineral processing index. Here are some common methods used in the beneficiation of iron ore: 1

    Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the
