Gold Shaking Table 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 |
|---|---|
| Deck size | 1,100×500 mm up to 4,500×1,850 mm |
| Capacity | 0.3–1.5 t/h on a full-size deck |
| Feed size | −2 mm, ideally deslimed below 45 µm |
| Feed density | 20–30% solids |
| Wash water | 0.5–1.5 m³/h |
| Stroke length | 8–30 mm, adjustable |
| Stroke frequency | 240–320 strokes per minute |
| Deck slope | 0–10°, adjustable in two axes |
| Motor power | 0.75–1.5 kW |
| Deck surface | Fibreglass or rubber-covered timber with riffles |
| Concentrate grade | High, often directly smeltable after cleaning |
| Recovery range | 60–90% depending on liberation and desliming |
What a Gold Shaking Table Is Used For
- Final cleaning of gravity concentrate
- Alluvial gold recovery in small plants
- Upgrading centrifugal concentrator product
- Tin, tantalum and other heavy mineral recovery
- Metallurgical laboratory test work
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 | Check deck slope and water distribution are even along the full feed edge; clear riffle blockages. |
| Weekly | Inspect deck surface for wear and riffle damage; grease head motion bearings. |
| Monthly | Check stroke length against setting; inspect drive belt and eccentric for wear. |
| Quarterly | Level the frame and re-verify deck geometry; inspect support rockers or slides. |
| Annually | Resurface or replace the deck covering; overhaul the head motion. |
Frequently Asked Questions
How much gold can a shaking table recover?
60–90% on liberated gold, and the figure depends heavily on desliming. Fines below about 45 µm behave hydraulically rather than by density and are lost across the deck, which is why a table nearly always follows a centrifugal concentrator rather than replacing one.
Why must feed be deslimed before a shaking table?
Slimes increase pulp viscosity and disrupt the density stratification the table depends on. Without desliming, the separation blurs and both grade and recovery drop. A hydrocyclone or settling cone ahead of the table is standard practice.
How do I adjust a shaking table?
Three controls interact: deck slope, stroke length and wash water. Increase slope or water to push more material to tailings and raise concentrate grade; reduce them to raise recovery at lower grade. Change one variable at a time and let the deck stabilise for several minutes before judging.
Can a shaking table replace mercury?
Yes, for the final concentration step. Combined with a centrifugal concentrator upstream, a table produces a concentrate clean enough to smelt directly, removing any need for amalgamation. This pairing is the standard mercury-free route for small-scale operations.
