Placed at the end of a high banker sluice for a final gold catcher you will be assured of capturing any missed gold. Legs are from crutches. The trap is 2-1/2" inches deep. The holes in the stratification tubes are 1/8" dia. and are spaced 1/2" apart and go through both sides.
Cut some hardware cloth of whatever mesh you want to the same diameter as your plastic pipe. Heat the bottom end of the pipe on an old hot plate or wood stove. When the plastic starts to melt, take it off and set it on the wire cloth. The plastic will solidify and "weld" the screen to the bottom of the pipe.
Most know the heavy visible gold (SpG. 15/19) will sink and where it's normally found in a river. In your case, the 25/1 micron gold (the unaided eye can see down to about 40 micron) can't overcome the surrounding surface tension of the water and is often carried in the middle third of the river's water level.
1 inch = 2.54 centimeters. 1 cm x 1 cm x 50 microns = 0.005 cc. 19.3g/cc x 0.005 cc = 0.0965 grams of gold per square centimeter @ 50 microns thickness. a) Measure the plated surface area in centimeters (1 mm = 0.10 cm) and multiply the length by the width.

Gold filled products are created utilizing a process that starts with a base metal such as brass (i.e. 90% copper and 10% zinc) or nickel on which a thin sheet of karat gold of the desired thickness has been "welded". The process begins by carefully fitting the base metal under a gold sheet of the desired karat alloy and thickness.
An Insight into the Micron. A micron is a unit of measurement equal to one-millionth of a meter. It describes the physical diameter of the pores in a filter that enables water to flow through while capturing contaminants. The lower the water filter's micron rating, the smaller the particles it can effectively trap and remove.

The principal behind the sluice box is the same no matter what design is used. Water carries gold laden gravels down the box and gravity ultimately separates the gold from the lighter rock and sand. In theory, it sounds simple, in practice, there is a little more to it. Most sluice boxes use riffles or obstructions blocking free flow of gravel ...

As for the gold on your cathodes you could try switching them over as anodes to redissolve the gold and redeposit on fresh cathodes at a lower current level. If copper is not present you can run at a higher current density to make the gold sludge off rather than depositing on the cathodes but first you need to figure out why the gold is adhering.
I'm thinking that if you're getting 100- or finer gold, don't go above 1/2 inch down from the top. Coarser material can have more material put in the bowl. 100-, only about a rounded tablespoon full. Hope this all helps. Google the blue bowl and you'll probably find a vendor with the full instructions online.
The standard micron thickness for gold-plated jewelry varies widely, often depending on the quality of the piece and the price point. However, a typical range would be between 0.5 microns to 2.5 microns. Lower-cost jewelry, often referred to as "flash" gold-plated jewelry, usually has a thinner gold layer, roughly around 0.5 microns or even less.
Fritz Haber (the German inventor of the Haber process) did research on the extraction of gold from sea water in an effort to help pay Germany's reparations following World War I. Based on the published values of 2 to 64 ppb of gold in seawater a commercially successful extraction seemed possible.
In the context of water filters, the micron rating refers to the size of the pores in the filter through which water can pass. The smaller the micron rating, the finer the filter and the more particles it can remove from the water. Water filters typically have micron ratings ranging from 0.5 to 100. The size of the contaminants that each filter ...
