Classification: CPC B | IPC B

Claim 1:
2. The spiral separator in accordance with claim 1, wherein the concentrate refiner region provides a cross-trough floor angle such that a balance of centrifugal and gravitational forces on the concentrate band is such that both the more-desired and less-desired materials would, if the balance of forces were maintained, migrate outwardly;
wherein the apparatus provides a refinement part of the concentrate refiner region at which least some of the less-desired material has migrated outwardly from a radial position corresponding to that of a preliminary concentrate band, and at which no substantial amount of the more-desired material has migrated substantially outwardly due to the balance of centrifugal and gravitational forces, so that a refined concentrate band is provided at the refinement part; and
wherein the splitting arrangement is provided at or immediately downstream of the refinement part to split the refined concentrate band from the rest of the slurry in the spiral trough.
