28/03/2015 · Spirals. The spiral, first developed for the treatment of beach sands, is used in iron ore concentration to treat minus 6 mesh ( mm) to 100 mesh ( mm) ores. Efficiency below 100 mesh decreases rapidly and spirals are ineffectual on finer materials. Spirals are normally operated at a pulp density of 25 % to 30 % solids.
