Sluicebox designs and their operating conditions adopted by small scale miners in PNG, who use them for the recovery of gold from alluvial deposits, vary widely. Some use small flowrates to increase the fine gold recovery at the expense of efficient separation while others use high flowrates resulting in high throughput rates with increased
A sluice box operated for extended periods with no new material being fed to it has an increased chance of losing some of its fine gold values. How much gold loss will depend on a multitude of factors, such as the type of riffle design, how much water flow, the type and weight of concentrates and the size and purity (specific gravity) of the gold.
We use computer aided design to ensure maximum fine gold recovery rates. We structurally reinforce our sluices to ensure that they endure years of work. MSI has many standard sluices available, but we always try to custom design each plant''s sluice to meet each mine sites particular requirements to achieve the highest recovery rates possible.

I do like the Wolf Trap. It works really well on fine flour gold all the way down to gold dust gets caught. It takes a bit more time to clean it out between buckets but the more I use it the easier it becomes to get the riffles in and out. It is great for smaller flake gold all the way down to super fine gold dust.
