Gold Spiral Wheel Concentrators provide Excellent Fine Gold Recovery from Black Sand concentrates. . Spiral Wheel Gold Concentrators make panning automatic - they can recover all sizes of gold -- from micron and flour gold to coarse nuggets. Some models like the Gold Magic can even work Wet AND Dry.
A spiral separator according to claim 5 wherein the pulp introduction means of each trough comprises a boil box extending radially inward of the trough, means for delivering pulp to the radially inwards extension at an angle to the horizontal and at an angle to the radial direction, and baffle means directing the pulp from the radially inwards ...
This paper will concentrate on recent work to expand the applicable size ranges that can be successfully treated by spiral separators and on increasing the unit capacity of these devices. Specific areas of investigation are: • The recovery of fine (<100µm) heavy mineral (>2.85 S.G.) • Increased spiral unit capacities to 7.0 t/h per start.
fraction of spiral concentrate has enriched to 37.74% Cr2O3 at feed rate of 1.2 m 3/hr, whereas by increasing the feed rate to 3 m3/hr, the quality of the concentrate fraction was drastically decreased to 26.57% Cr2O3. There is no significant change in the quality of the concentrate fraction of spiral
Our spiral separators have a diameter of +/- 950 mm. Gravity Separators for coal.
