A Review of Spiral Technology for Fine Gravity Beneficiation

Fig. 3 illustrates the optimum feed conditions for the FM1 fine mineral spiral at a values recovery of 50% viz. low feed rate 0.8 t/h and feed pulp density of 35-36 %solids. The benefits of using the FM1 spiral for the treatment of fine grained silica sand, tin tailings, iron ore and copper were also investigated (Richards et al 2000).

Spiral Classifier for Mineral Processing

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material

Common Types of Spiral Classifier Used in the Mineral

Mineral processing experts suggest that the single spiral classifier should be selected as far as possible under the determined processing capacity. According to statistics, the working load of the double spiral classifier is 0.6-0.75 times than that of the single spiral classifier, and the efficiency is relatively low.

Oct 15, 2014· The mineral size recovery curves of roughing, cleaning and re-cleaning spirals from two Canadian iron ore processing plants are estimated using the results of several sampling campaigns. A similar behavior of the spirals is observed in both plants in spite of the fact that the plants use different types of spirals.
