Mineral processing

Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

Magnetic Separation

Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet. These minerals

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property. These data are timesaving for mineralogists who

Iron is very ferromagnetic, and therefore it is quite sensitive to being magnetized by magnets. This is the reason why we can extract iron objects, as in the case of a mixture of iron and sulfur.

10/07/2015 Wet magnetic separation is the commonly used technique for mineral processing (Kelland, 1973, Oberteuffer, 1974) and is suitable for the recovery of fine ferro and diamagnetic mineral (Shao et al., 1996). The quantity of magnetic particle in SMR is comparatively lower; thus a wet separation will provide better separation than dry. The high intensity separator was chosen to have a

The SEM analysis demonstrated that magnetite is located primarily on the surface of alumosilicate spheres and has
