When the deslimed feed is fed to the spiral, high concentrate grades has been produced with very high recoveries as high as 98%. INTRODUCTION Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used
Basically the different wet classifiers are gravity settling tank, cone classifier, double cone classifier, hydrocyclone classifier, spiral classifier, and rake classifier. Gravity settling tank is the simplest type of classifier. Here the separation is based on the influence of gravity and terminal falling velocity.

If slime is in excess of 10% by weight, desliming prior to spiral concentration will almost certainly result in improved spiral performance. In general, a specific gravity difference of at least 1 is required between light and heavy particles for successful gravity separation. Feed distributor
Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.
The optimized classifier wheel geometry produces the finest cut points and high yields that have not been possible with production scale conventional air classifiers with only one classifier wheel. The special dispersion zone directly in close proximity to the classifier wheel uses clean gas to efficiently disperse the material to be classified.
