FINE GOLD The Recovery
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.
The Physics
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.
The Matting
Traditional riffles are too chaotic for fine gold. You need **Vortex Matting** or specialized rubber mats that create micro-eddies to trap the flour.
- Deep-V Rubber Mats
- Dream Mat / Vortex Tech
Classification Logic
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.
Screening is Survival
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.
The Loot Bag
Strategic weight valuation. Calculate the spot yield of your discovery and bridge the target gap to a physical ounce.
"The gap to a full ounce is only 30.10 grams..."
Fine Gold Kit
Black Sand + Flour Gold Cleanup Kit
The gear stack for concentrates, black sand and 50–100 mesh gold where bad classification and surface tension lose values.
Finishing pan
Final cleanup
A small finishing pan gives better control once only black sand and fine gold remain.
Rare earth magnet
Black sand control
Removes magnetite in stages so you can see fine gold without dragging it out aggressively.
Micro vials + snuffer
Flake recovery
Keeps small recoveries secure and separated by test spot or cleanup batch.
Surfactant / finishing aid
Surface tension break
A tiny drop stops flour gold floating across the pan during final cleanup.
