The recovery of placer gold from 20 mesh to 150 mesh in common sluicebox configurations was investigated. Two types of riffles, 1-10H expanded metal (1.5"x.75"x.25") and 1.25" angle iron riffles (dredge riffles), were used in conjunction with 3/8" thick "Nomad" matting for 25 tests. The effects of variations in upper feed size, water flow rate, sluice gradient, and solids feed rate on the ...

A placer miner responds: we don’t waste gold – Yukon News

Sep 26, 2017  Perhaps Clarkson was too modest to explain that he is a pioneer in placing small (human safe) radioactive isotopes amongst a pre-sluiced ore pile and then finding them again in the sluice box. That method allows for determining your recovery rate. His in-depth and published study found that most sluice plants recover about 95 per cent of the gold.

Long toms can produce greater volumes of concentrates but are simple and effective when operated with sufficient water volume and velocity. The dual cell jig tailings tested had from 5 to 55 fine grams/m3 mostly due to the loss of fine (-50 mesh [#] gold).
