Sluice Box Design [Archive] AMDS Adventure ForumHi, The Klondike Placer Miners Association commissioned what in my opinion is one of the best studies ever done on sluice box design. They actually irradiated gold to make it temporarily radioactive so gold losses could be traced with near accuracy.
Canada's Silencer Laws | Silencers have been illegal in Canada since 1900, and it doesn't look like that's going to change any time soon. A 2017 petition to the Canadian government, requesting permission for the ownership and use of sound moderators by licensed Canadian gun owners for .
A history of gravity separation at Richards Bay MineralsA history of gravity separation at Richards Bay Minerals result in blockage of the mouth organ splitters and inserts, affecting the even distribution of slurry feed to the separation surfaces. Cleaning the aforementioned splitters and slots was a tedious chore not looked forward to by the operating crews.
How it Works Gold MagicHeavy weight materials (gold) sink to the lowest point at the joining of riffle and the pan (1C) and commence rotating toward areas (2,3,4). ( Area 2) This is the riffle transition and large nugget recovery area. Nuggets too large to spiral up the riffle in area (3) into concentrate cup (4) will remain in area (2) until visually sighted and removed.
