— Different spiral concentrator profiles. Spiral usually operates at 40-50% solids and the design can consider employing a hydrocyclone as the first separation stage. In this way the underflow can be directed to the spiral. Once the slurry is in the spiral, light and heavy mineral are classified according to their densities. In general, heavy ...
