Sommaire: Sluiceboxes can provide a much higher concentration ratio than most other gravity concentrators (up to 50 000:1) at very high overall placer gold recoveries (greater than 99%). They are also very reliable, inexpensive and simple to operate. This combination is very difficult to beat and explains why the sluicebox is still the most important placer gold concentrator in Canada's Yukon Territory.
A sluicebox is a rectangular flume containing riffles on matting, through which a dilute slurry of...
