ABSTRACT:
A spiral separator for the wet gravity separation of solids of different specific gravities has a number of helical sluices or spirals mounted about a vertical column, the bottom of each spiral being substantially straight in cross-section and inclining upwards from inside to outside of the spiral, the pitch of the outside of the spiral being substantially uniform, but the angle of the spiral bottom to horizontal, and therefore the pitch of the inside part of the spiral, varying, this angle and the inside pitch of the spiral being greater in the upper part of the spiral than in the lower part.
