Abstract
Apparatus for the magnetic separation of feebly magnetic materials from a slurry comprises a number of matrix containers which are movable along a path between a number of pole pairs. The slurry passes through the matrix containers and is received in launders under the path, the non-magnetic constituents being collected in launders below the pole pairs and the feebly magnetic constituents in zones of low magnetic intensity. The matrix containers can be removed from the path individually for cleaning.
Claims15
In a separator of the type including:
- magnetic means for establishing zones of high and low magnetic density;
- matrix container units comprising a series of separate matrix container units which are movable in a path through said zones of high and low magnetic intensity;
- matrix means within each matrix container unit;
- feed means supplying slurry to said matrix container means;
- washing means for washing out material entrapped in the matrix means;
- launder means receiving respectively matter passing through said matrix container means at at least said high magnetic intensity zone and said low magnetic intensity zone;
- and
- moving means operatively connected to said container means for moving said matrix container means through said high and low magnetic intensity zones;
- the improvement wherein the moving means comprises a path through said zones established by said magnetic means, means for transferring said container units onto said path, and means for providing a moving force to said units to move the container units as a continuous matrix through the magnetic zones, and wherein the matrix container units are removable and replaceable when in the means for transferring without interrupting the continuous movement of the container units along said path.
