Experimental device. The device is composed of a fork-like magnet holder that keeps two 20 × 5 × 5 mm 3 NdFeB magnets with 1.3 T as remanence field (Supermagnete , Gottmadingen, Germany), symmetrically placed at a fixed edge-to-edge distance of 3 mm. A rotatory motor moves the magnets holder, via a central shaft, …
There are five major separation methods. In the filtration method, the mixture is passed through a filter paper, the liquid gets strained to leave behind suspended particles. The centrifugation method is used to strain the tiny suspended particles which could not be captured by the filtration method.
Magnetic-activated cell sorting (MACS) MACS (Miltenyi Biotec, Bergisch Gladbach, Germany) is a cell separation technology based on the use of monoclonal antibody-conjugated magnetic beads. After incubating beads with a cell suspension, the cells are passed through a column within a magnetic field. Cells carrying the magnetic beads …
Magnetic separation technology plays an important role in upgrading such low-grade iron ores, because the magnetic separation process possesses the combined advantages of large capacity and low operating cost, as well as being environmentally friendly. This chapter first introduces the principles and recent advances in magnetic …
Magnetic separation will reduce this potential by allowing systems to operate more efficiently and eliminating the need for such services. By eliminating the need for repairs, the planet avoids exposure. Widening the Impact. BPS' magnetic separator technology provides a win on all fronts for customers to enjoy well into the future.

The magnetized plate must be periodically inspected and cleaned because its efficiency decreases if tramp iron particles ...
The fine sand particles pass through the iron mesh and remain behind. (4) The method of sieving is also used to separate similar objects of different sizes. The cashew nuts of different sizes are separated in cashew nut factories by the process of sieving. Magnetic Separation . Magnetic separation means separation of a mixture by using a magnet.
