"The Humphrey's spiral is a static gravity separation device which cannot be adjusted to match short-term variations that occur in the feed. Any disturbance in the feed grade, per cent solids or flow rate affects substantially the recovery and grade of concentrate.

The thermal performances are evaluated by numerical method using CFD code. Various models of spiral-tube GHEs installed in a borehole and backfilled with silica-sand were simulated. In comparison with the conventional U-tube GHE, the performance of spiral-tube GHE increases of % in the laminar flow and of % in the turbulent flow.

Attrition scrubbers are used to scour particulate surfaces, removing undesired materials and breaking down clays – cleaning and desliming the particles prior to other treatment processes. It is the friction between the particles, created by turbulence and supplied by the machine's impulsion, that provides the highly efficient cleaning action.
