Recovering nuggets is easy. Recovering 100-mesh flour gold is a science. Most prospectors lose 50% of their values in their tailings because they ignore the fluid physics of fine gold.

Fine gold has a massive surface-area-to-weight ratio. This makes it susceptible to **surface tension**, causing it to float away on top of the water.
Tactical Tip:
Always use a surfactant (like Jet Dry) in your finishing equipment to break surface tension.
Traditional riffles are too chaotic for fine gold. You need **Vortex Matting** or specialized rubber mats that create micro-eddies to trap the flour.
The most important step in fine gold recovery is **classification**. If you have a 1-inch rock and a 100-mesh gold flake in the same box, the rock will act as a bulldozer, washing the flake out of the riffles.
For final cleanup, شما must screen your concentrates down to at least **20-mesh**, ideally **50-mesh**. This ensures every particle in your machine is of a similar size range.
