2019year3month5day Subsequent mineral separation by density was achieved using a Wilfley-table. The heavy mineral fraction was then further parted by magnetic separation (Frantz magnetic separator) in two steps (0.5 A and 1.5 A current). Minerals that were not magnetic at a current of 1.5 A were further separated by heavy liquids (3.32 g/cm 2). The mineral ...

High gradient magnetic separation (HGMS) makes possible the efficient separation of very weakly magnetic particles of micron size for which conventional magnetic separators are ineffective. Filamentary ferromagnetic materials placed in large (10 kOe) background fields are used to obtain large surface areas of high field gradients. Potential applications in
