TYPICAL MASS BALANCE FOR THE USE OF SLUICE-BOXES
- 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 or 0.01% of the material is amalgamated!
- 99.99% of the material is discharged completely free of mercury contamination
- Cleaner sluice-box tailings are recycled to feed
