building a sluice box. 2018-9-20not an expert but my smaller sluice used 38 expanded metal with a combination of miners moss, carpeting, and stone matting underneath maybe even some angle iron or something to catch nuggets firstor my failed experiment, i used expanded metal and no riffles because i was after sub gram gold, mostly minus 20 mesh.
after dumping each load of gravel into the sluice box, check the riffle section for large waste rocks that may be lodged in the sluice. flick these rocks out of the riffles with your fingers. when large rocks are allowed to rest in the riffle section they will cause the current to wash out all the concentrates from the immediate area of the rock.
this is something i am very much a rookie with. i know the box needs to be level on the horizontal, but what is the optimum angle or slope if you will to set your sluice box at. when i say optimum i guess i am thinking what slope or angle of attack on a sluice box traps the most gold (flour gold, flakes, etc etc).
bc placer sluice boxes and highbankers 2017-8-30 183; in a quot;mat/screen/rifflesquot; sluice box, when the angle and water flow are just right, (most) gold will be retained behind the riffles, while most of the regular sand and some of the black sand (and probably some of the fine gold) are flushed out.

a sluice can function very well, even at the wrong angle, if the riffles, and water flow, and all other things are in concert with each other so that the gold does get trapped. that being said, sluice angle, riffle height and configuration, and water flow are the most important things in my experience.

water speed and volume are critical! even in a poorly designed sluice, if you have the volume and speed of water dialed in you will still catch gold more effectively than using a pro high end sluice that's set up wrong. furthermore, the angle at which the sluice boxes lay are also very important.
the sluice box riffle tray sits on top of a carpet that traps the fine pieces of gold. when the time comes to clean out your sluice box and collect the gold, you pull out the riffle tray and wash the carpet out inside your bucket. the fine material that was trapped in the carpet will then be in your bucket for you to easily pan out later.
