Magnetic Methods for the Treatment of Minerals

This book treats magnetic separation from the point of view of both the engineer in the field who operates magnetic separators and the research scientist in the laboratory. It emphasizes those aspects of magnetic separation where lack of support in fundamental research is most evident. The intention is to bring the engineer and the scientist closer …

Towards waterless operations from mine to mill

Magnetic separation. Magnetic separation uses magnets and magnetic fields to separate minerals. Separation selectivity is based on differences in magnetic properties of minerals that are either inherent in certain minerals or can be induced with various pre-treatment methods (Faris et al., 2019, Koleini and Barani, 2012). Magnetic …
