Abstract
This invention relates to a take-off assembly for mounting in a spiral separator. The take-off assembly includes an adjustment tongue and a mating member containing a transverse aperture for receiving the adjustment tongue. The mounting member has a surface surrounding the adjustment tongue which is substantially flush with the top surface of the adjustment tongue. There is also provided an undercut for obtaining an undercut of concentrates particles from pulp flowing in the spiral separator whereby tailings and/or middlings contained in an upper portion of the pulp above the concentrates particles may flow across the transverse aperture. There is also provided a spiral separator for gravity separation of minerals containing the take-off assembly and a method of taking undercuts including using the abovementioned take-off assembly in the spiral separator.
