Forces of attraction → this force is what we see when we bring the magnet closer to the mixture. Magnetic separation uses the magnetic properties of minerals, which is why depending on the type of minerals we want to separate, we must use a magnet with more or less Gauss: - 500 - 5,000→ strongly magnetic (magnetite). - 5.000 - 10.000 → ...

Similarly, immobilization of glycoconjugates on ...
Wet High Intensity Magnetic Separators incorporate a matrix which is magnetized by an externally produced magnetic field. The matrix amplifies the applied field and produces very high gradients. The feed slurry flows through the matrix which captures the paramagnetic particles while the diamagnetic particles are washed through.
