The precision cleaner of the gravity circuit
When a gravity circuit needs a final, visually clean, smeltable concentrate, the shaking table is the device that delivers it. The Gemini 6-S style table uses a riffled deck, a controlled water film and an asymmetric back-and-forth stroke to fan out particles by density, so gold, sulfides and gangue separate into distinct bands you can split with adjustable cutters. Few other separators give you that level of visible, fine control over the final grade.
How a shaking table separates gold
Feed slurry spreads across the high corner of a slightly tilted deck. The fast-forward, slow-return stroke nudges heavy gold along the riffles toward the concentrate end, while cross-flowing wash water carries light gangue down the slope to tailings. Middlings band between the two and can be re-treated for extra recovery. Deck slope, stroke length, feed rate and wash-water volume are all tunable, which lets an operator dial in grade versus recovery for the specific feed rather than accept a fixed compromise.
Where the table sits in the flowsheet
- As a cleaner on rougher concentrate from a centrifugal concentrator, jig or spiral chute, which is the most common duty.
- As a primary concentrator for small alluvial or hard-rock free-gold operations.
- For recovering tungsten, tin, tantalum and other heavy minerals where the density contrast is high.
A single deck handles roughly 0.1 to 1.5 tons per hour depending on size and feed, and multi-deck arrangements multiply throughput in a small footprint. Because the separation is visible, the table doubles as a process check; operators can see at a glance whether the upstream circuit is liberating and recovering gold properly, which makes it a useful diagnostic as well as a concentrator. Wear is limited mainly to the deck surface and riffle covering, so running cost is low and predictable.
Sized into your circuit
Tables are chosen by feed size, throughput and how clean the final concentrate must be, and they usually run after a rougher stage rather than alone. Xinhai supplies them individually or as part of a complete gravity concentration circuit under our EPC+M+O model. Read our gravity concentration guide or contact us with your feed details for sizing.

Frequently Asked Questions
Is a shaker table a rougher or a cleaner?
Most often a cleaner. It takes rougher concentrate from a jig, spiral or centrifugal concentrator and upgrades it to a smeltable, high-grade product. On small alluvial or free-gold operations it can also act as the primary concentrator. We position it in your circuit based on feed grade and the final concentrate spec you need.
What throughput does one table handle?
A single deck typically processes 0.1 to 1.5 tons per hour, depending on table size, feed size and how clean the concentrate must be. For higher capacity we use multi-deck tables, which stack throughput in a compact footprint. Send your feed rate and we will recommend a single or multi-deck configuration.
Can it recover minerals other than gold?
Yes. Any time there is a strong density contrast, a shaking table works well, so it is widely used to concentrate tin, tungsten, tantalum and other heavy minerals as well as gold. The deck adjustments are tuned to the target mineral's size and density for the best grade and recovery.
How much does a gold shaking table cost?
Pricing starts around US$7,899 per set and depends on table size, the number of decks and the deck material. Because tables usually follow a rougher stage, we can quote the table alone or as part of a complete gravity circuit. Share your feed details for an accurate proposal.
