The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral concentrators offer a relatively simple unit operation that translates to low capital and operating cost.
