Feed: alluvial gold ore: 100m3 or 180t (one day) = 100% Rougher sluice-box pre-concentrate: 180kg = 0.1% Cleaner sluice-box concentrate: 18kg = 0.01% Only the cleaner concentrate…
From visual observances, three modes of particle transport due to flow rates were identified. At low flow rates, particles build up against the riffle until it becomes full, and then roll/…
Would allow a lower flow rate , shallower slope, and the effect of differences in specific gravity would be more pronounced due to the lower influence of particle sizes
