Dec 17, 2012· Sluice boxes made of steel sheet metal, aluminum & plastic come in all sorts of designs, length, width, riffle configurations.

Gold in my tailings… tuning and testing.
Feb 01, 2016· It is always exciting to see gold in your Sluice Box right away – especially when you are trying to test a new piece of equipment.

Apr 12, 2013· Fast water moving down the sluice pushes the gold down the box. If the water is moving slow enough, the gold will drop out quickly.

3.Replace the carpet with a better sluice matt. The wire mesh traps a ton of rocks. If it builds up too high the gold flows right over it. I still gave this 3 stars, it worked and trapped gold, but I've now turned it into a box that doesn't fold and put a few hours into replacing the mat with a one piece mat, so I'll see how that works.
In the desert, the drywasher is the tool of choice. Again, this is because of the lack of water. A drywasher uses air and vibration, rather that the flow of water, to separate gold out from the lighter material. Drywashers are not as efficient as sluice boxes, but they still work pretty well when they are all set up correctly.
Hot bath the black sand, and give it a nice stir. 2. Crushing the Black Sand. Sometimes one black sand particle will merge with several other grains of black sand, and capture some gold in the process. If this has happened to enough extent, you might decide to crush it to extract the gold.

Sluice boxes process material best when receiving it from a steady feed. Too much material dumped at once into a sluice box has a tendency to overload the riffles and choke off the concentrating-action behind the riffles. This will cause gold to wash right through the sluice box as if there were no riffles present at all.

I know this viewpoint is not popular with some prospectors, because they do not want to chance losing a bigger piece of gold that is allowed to get so close to the ...
