1. A device for separation of a mixture comprising a magnetic solid and a non-magnetic solid in a fluid flowing through the device when subjected to a magnetic field from a magnet disposed proximate to at least a portion of the device, the device comprising:
a separation chamber extending from a proximal end to a distal end;
the proximal end defining an inlet;
the distal end defining a first outlet and a second outlet; and
the first outlet and the second outlet are spaced apart from each other by a distance and are in fluid communication with the inlet and the separation chamber;
the separation chamber providing a path for fluid flow from the inlet to the first outlet and the second outlet;
the inlet being configured to receive the fluid comprising the mixture of the magnetic solid and the non-magnetic solid;
the separation chamber having a region that is configured to subject the fluid flowing through said region to the magnetic field to thereby separate the mixture into a first portion and a second portion;
the first outlet being configured to receive the first portion of the mixture from the separation chamber;
the second outlet being configured to receive the second portion of the mixture from the separation chamber;
the first portion being enriched with the non-magnetic solid relative to the second separated portion; and
the second portion being enriched with the magnetic solid relative to the first separated portion;
wherein:
the separation chamber has a cross-sectional shape that is triangular; or the device further comprises a magnet and the magnet is disposed above the separation chamber to pull the magnetic solids upwards towards the second outlet while the non-magnetic solids settle downwards towards the first outlet.
