A complete range of spirals for minerals concentration

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.

An analytical approach to explain complex flow in spiral concentrator

The most representative roughness height of the spiral trough was found to be 138.4 μm and the wall contact angle of the spiral surface was 88.14°, measured in the water phase. The experiments showed that the free surface shape and the position and width of the bubble line in a water-only flow reached a steady state after 1.25 spiral turns.

The geometry used in the present simulation study is the LD9 coal spiral concentrator with six turns (Fig. 1).Since this LD9 spiral trough profile is very long, with a continuously curved nature, high ash coal is treated with it (Balderson, 1982)plete details of the geometry dimensions are presented in Table 1.The variables used in CFD …

Investigation of residence time and fluid volume in spiral

The mean residence time ( τ) is estimated at 7.5 s and is roughly constant for the three spiral feed rates. The 7.5 s mean residence (τ) for a 60 l/min feed rate (Q) corresponds to a volume ( V = τ × Q) of 7.5 L in the spiral. The invariability of the mean residence time with the spiral feed rate confirms that the fluid volume in the spiral ...

Gravity Spiral Concentrator Working Principle

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)
