Moreover, this new three-stage in one spiral technology allows for the coal to undergo separation thrice, instead of twice when using a conventional spiral such as the SX7 and MX7."Traditional" spirals usually provided a cut point between 1.6 g/cm³ and 1.8 g/cm³, but the SX10 provides an even lower cut point, between 1.5-1.55 g/cm³ ...
efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Spirals require a minimum of maintenance and upkeep, and offer a relatively simple unit operation that translates to low capital and operating cost.
Spiral concentrators are widely used in fine coal beneficiation as they offer several advantages that include low operating and capital costs, being simple to operate, low maintenance and high tolerance to variability in feed conditions (Erasmus, et al., 2018). Fine coal slurry (75 – 3000 µm) is fed to the top of a spiral and gravitates ...
