Iron Ore Efficient Magnetic Separator Steps - Consuol ...

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

Magnetic separation - Wikipedia

Magnetic separation techniques are also used in microbiology. In this case, binding molecules and antibodies are used in order to isolate specific viable organisms, nucleic acids, or antigens. This technology helps isolating bacterial species to identify and give diagnostics of genes targeting certain organisms. When magnetic separation techniques are combined with PCR (polymerase chain ...
