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. [ 9 ] This technology helps isolating bacterial species to identify and give diagnostics of genes targeting certain organisms. [ 9 ]
An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals. [1]
Ion separation is another application of magnetic separation. The separation is driven by the magnetic field that induces a separating force. The force differentiate then between heavy and lighter ions causing the separation. This phenomenon has been demonstrated on test bench and pilot scale. [1]
Magnetic separation; Oil-water separation, gravimetrically separates suspended oil droplets from waste water in oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industries; Precipitation; Recrystallization; Scrubbing, separation of particulates (solids) or gases from a gas stream using liquid.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
The process is usually carried out in the vertical furnace, the charge is top-down under the action of gravity, through layer by layer heating and reduction reaction, and finally obtain magnetic iron ore, so as to improve its magnetic separation performance, and facilitate the subsequent beneficiation and smelting process.
There are three steps involved in the magnetic separation process: Bind – Microbeads bind to the desired target, relative to the specific affinity of the ligand on the surface of the beads. Wash – Microbeads will move to the side of the tube in response to a magnetic field, along with the bound material. This happens quickly and efficiently ...
DNA analysis have supported the combined use of both this technique and Polymerase Chain Reaction (PCR). [1] Another laboratory separation tool is the affinity magnetic separation (AMS), which is more suitable for the isolation of prokaryotic cells. [2]
