Abstract
A method for high grade magnetic separation using a matrix having one or more magnetizable matrix elements, wherein each element comprises a pair of poles aligned substantially parallel to a direction of flow of a slurry fluid containing particles to be separated, whereby a rear fluid vortex attributable to the upstream pole extends substantially to meet a front fluid vortex attributable to the downstream pole.
Claims4
A method of magnetic separation of magnetisable particles contained in a fluid, the method comprising the steps of:
- magnetising one or more magnetisable elements disposed in a flow path of the fluid, each element having a pair of magnetisable poles substantially aligned with the direction of fluid flow and spaced apart along the direction of fluid flow such that a rear fluid vortex attributable to the upstream pole extends substantially to meet a front fluid vortex attributable to the downstream pole.
A method of separating materials, the method comprising providing at least one magnetisable matrix including one or more matrix elements, each matrix element including a pair of poles;
- aligning the poles substantially parallel with the direction of a slurry fluid flow containing material to be separated;
- and magnetizing the matrix by way of magnetic source, wherein the poles are spaced apart so that front and rear vortices attributable said pair of poles link up to provide a single vortex of increased stability.
