RED is most often used to separate two or more paramagnetic minerals into separate finished products (or semi-finished products for further polishing) in the early stages of a dry separation process flowsheet. Additionally, a RED typically operates at higher unit capacity than a RER separator. RER is more commonly applied to residual streams ...

The separating magnetic force is directly proportional to the product of the magnetic flux density, and its gradient. When using an inclined feed, the Frantz Isodynamic separator (see Figures. 1(A) & (B)) has three inherent variables. These are the field strength (current used), the side slope, and the forward slope.
