Gravity recovery systems for placer and alluvial gold — washing, centrifugal concentration, and fine shaking-table separation that recover free gold from gravel without chemicals.

Batch centrifugal concentrators that recover fine free gold from 0–6 mm feed using an enhanced-gravity fluidized bed. Proven recovery of +38 µm particles with strong capture of the 10–38 µm fines that sluices and pans lose — the primary concentrator of every serious placer plant.
| Model | Capacity (t/h) | Max Feed (mm) | Water Flow (m³/h) | Motor (kW) |
|---|---|---|---|---|
| STLB-20 | 0.5–1 | 6 | 2–3 | 0.75 |
| STLB-30 | 2–5 | 6 | 4–8 | 2.2 |
| STLB-60 | 6–15 | 6 | 12–20 | 5.5 |
| STLB-100 | 15–25 | 6 | 25–35 | 7.5 |
Standard specifications — final confirmation at order. Recovery rate depends on feed size distribution and gold liberation; test-plant processing available for your gravel.

The final cleaning stage that turns concentrate into salable gold. 6S tables separate by density with adjustable stroke, frequency and tilt — three deck types match coarse sand, fine sand, and slime fractions from your concentrator concentrate.
| Deck Type | Feed Size (mm) | Capacity (t/h) | Stroke (mm) | Motor (kW) |
|---|---|---|---|---|
| Coarse Sand Deck | 0.2–2 | 0.8–1.5 | 14–24 | 1.1 |
| Fine Sand Deck | 0.074–0.5 | 0.4–1.2 | 10–20 | 1.1 |
| Slime Deck | 0–0.15 | 0.2–0.6 | 8–16 | 1.1 |
Standard specifications — final confirmation at order. Complete with table deck, head mechanism, feed launder and water distributor.
Centrifugal concentration recovers the 10–38 µm fraction that sluices and pans lose — the difference between 50% and 90%+ recovery on many deposits.
Closed water circuits with settling ponds keep fresh-water use low — critical at remote dry-season operations.
Full gravity processing replaces mercury amalgamation — safer for operators and accepted by buyers and regulators.
Skid-mounted modules scale from 5 to 100 t/h and relocate between pits in days, not months.
