New spirals have been developed that do not use wash water. These new units have modified cross sections and only one concentrate-take-off port, which is. located at the bottom of the spiral (Photo 6). Spiral concentrators are used for the processing of heavy mineral-bearing beach deposits in Florida and Australia.
