Alluvial Gold Wash Plant Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Typical capacity | 10–150 t/h feed, by unit sizing |
| Stages | Feed hopper → scrubber → trommel (10–16 mm) → fine screen (<2 mm) → concentrator + sluice/jig → table |
| Concentrator feed | Screened to below 2 mm before the centrifugal concentrator |
| Coarse gold recovery | Sluice or jig, treating the 2 mm and above fraction |
| Water use | 3–8 m³ per m³ of feed in heavy clay, recycled through settling ponds |
| Power | Diesel or electric by stage; sized as one load, not per machine |
| Footprint | Skid or trailer-mounted stages for a mobile plant; static frame for a fixed site |
| Wet-season provision | Covered stockpile, sized settling ponds, pit dewatering pump |
Alluvial Gold Wash Plant: Uses and Applications
- Alluvial and eluvial gold operations running through the rainy season
- Clay-bound gravel that a single machine cannot process cleanly
- Reprocessing old tailings and amalgamation waste
- New ground where both coarse nuggets and fine gold are present
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every shift | Confirm water is reaching every stage evenly; check each screen for blinding and each concentrate point for security. |
| Weekly | Inspect scrubber and trommel liners, fine screen panels, and sluice or jig riffles for wear. |
| Monthly | Service settling ponds and water recycle pumps; inspect concentrator bowl and fluidisation holes. |
| Rainy season start | Check pit dewatering pump, stockpile cover and pond capacity before the rains, not after the first storm. |
Frequently Asked Questions
What should the plant actually look like for muddy ore?
Feed hopper with a grizzly, a rotary scrubber to break up clay, a trommel at roughly 10–16 mm to reject stones, a fine screen under 2 mm to prepare the concentrator feed, a centrifugal concentrator for the fine material followed by a shaking table, and a sluice or jig for the 2–16 mm fraction. That split is what lets the plant catch both coarse and fine gold instead of losing one to protect the other.
Do I need every stage from day one?
No. Many operations start with a trommel and a sluice, add a scrubber once they see how much clay their ground actually has, and add a centrifugal concentrator and table once fine-gold losses justify it. Tell us your ore and budget and we will sequence the build rather than sell you everything at once.
What recovery can I expect overall?
On liberated gold, a well set-up plant recovers 85–98% on the fine fraction through the concentrator and a broadly similar range on coarse gold through a properly run sluice or jig. The honest answer depends on your ore, so we recommend a sample test before finalising the setup.
How is this different from buying the machines separately?
The individual machines can each work well and still under-perform together if the sizes between stages do not match: a fine screen too coarse for the concentrator, or a scrubber undersized for the trommel behind it. Specifying it as one plant means every stage is sized against the one before and after it.
