Gold Screw Spiral Separation for Fine Gold Recovery
A Gold Screw is a spiral separator that uses a rotating spiral to pull fine gold away from black sand and other heavies, reducing a large concentrate down to a small, gold-rich fraction. It sits between a hand pan and a full powered panning wheel in a prospecting setup, and it pairs naturally with the rest of your gold-recovery gear. We have run Gold Screw units on concentrates from both drywasher and sluice operations, and the spiral consistently captures fine gold that would otherwise take hours of careful hand work. If you want to compare recovery methods, see our stackable Gold Cube concentrators and powered Gold Magic spiral wheels alongside the Gold Screw.
Choosing Gold Screw for Field Use vs Home Cleanup
Gold Screw systems work in both remote field settings and stationary home stations. For field use, they are built for portability, so you can carry one alongside your metal detectors and your digging tools, process concentrate on site, verify your ground immediately, and cut the raw weight of material you pack out. For home cleanup, the Gold Screw drops into a recirculating water loop so you can work through backlogs from several outings at your own pace. The spiral handles varying concentrate densities without clogging or constant recalibration, and if you run a highbanker or a high-volume sluice, a home station built around a Gold Screw sharply shortens your final cleanup.
Improving Recovery Rates With Gold Screw and Panning
A Gold Screw reduces concentrate volume before final panning, which cuts the tedious hours spent hunched over a pan. After running material through the spiral, you are left with a small, manageable fraction of heavy material. We have found that combining the bulk separation of a Gold Screw with solid gold panning basics and a quality finishing pan from our gold pan range produces the highest recovery rates, securing fine flour gold that hand panning alone can lose to the tailings.
Gold Screw Compatibility With Classifiers and Prospecting Gear
Gold Screw systems work best when material is pre-classified to remove oversize rock and organic debris. Running concentrate through a screening classifier before it reaches the spiral prevents jams and keeps a smooth, uninterrupted flow. Whether you use 20-mesh or 30-mesh classification, tighter screening improves fine gold separation and yield.
