Spiral (Concentrators)
The major factors that makes this concentrator attractable for its application is low capital and operating cost, higher recoveries and no reagents used. The drawback of spirals is that they are density separators that are unable to obtain a D 50 lower than 1.65 g/cm 3 but tend to have a D 50 between 1.7 and 2.1 g/cm 3 and misplaces a ...
