A discussion of magnetic separation techniques for

magnetic separators. Dry magnetic separation is more controllable since the separation medium is air rather than water. Separating particles from one another is naturally easier without having to fight drag forces created by water. This creates a distinct advantage to using rare-earth dry magnetic separators: the ability to produce a variety of ...
