Observation of iron ore beneficiation within a spiral ...

2016-2-2  Spiral concentrators are used in the processing of ores composed of minerals with different densities. A unit is composed of a profiled channel swept helically around a central post creating a spiralling trough. Commonly used spirals have between three and seven turns, with a diameter between 0.4 and 1 m (Palmers and Vadeikis, 2010).
