Working Principle
The Gemini Shaking Table is typically driven by an electric motor, which rotates an eccentric shaft connected to a shaking rod. This rod converts rotational motion into the reciprocating movement of the deck. Ore slurry is fed through a feed box located at the top corner of the table, while transverse flushing water is added from a separate water channel.
Under the combined action of gravity, transverse water flow, inertia and friction from the table’s asymmetric motion, mineral particles stratify by density and size. Heavier and coarser particles move differently than lighter ones, resulting in longitudinal movement along the table and lateral spreading across its slope. As a result, the particles gradually fan out and are separated into concentrate, middling, and tailings, discharged from different zones.
This method uses no mercury or chemicals, making it economical and environmentally friendly. It supports multi-stage separation and accurately recovers mineral particles such as gold, lithium, copper, and tin—ideal for mineral processing at various scales.
