The LIPU Gemini Shaker Table separates mineral particles by differences in specific gravity, particle size, and settling behavior. It is used for fine mineral concentration and laboratory testing, particularly in gold recovery and other gravity separation applications.
A Gemini Shaker Table is a gravity separation device with a riffled deck that moves under a controlled shaking motion. Feed slurry and wash water spread across the deck. Differences in particle density, size, and movement cause the minerals to separate into distinct bands.
The resulting streams can include concentrate, middlings, and tailings. Product quality and recovery depend on feed characteristics, deck settings, water flow, and operating conditions.
Gemini Shaker Tables are used to concentrate fine heavy minerals from prepared feeds. Typical applications include:
Feed preparation and particle-size distribution affect separation results. Material testing can help determine whether a shaking table is suitable for a specific ore.
Prepared slurry is fed onto the deck while wash water flows across the surface. The deck’s reciprocating motion moves particles along the table, while water flow carries lighter particles across it.
Heavier particles tend to follow a different path from lighter particles. Adjustable deck inclination, stroke, and operating frequency help operators control the separation according to the feed and target products.
A Gemini Shaker Table is generally used after grinding and classification, when the feed has been prepared for gravity separation. Depending on the process, concentrate, middlings, and tailings can be collected separately for further treatment, reprocessing, or disposal.
The equipment arrangement depends on the ore characteristics, required capacity, and the rest of the processing circuit. See our gravity separation equipment for related options.
The machine typically includes a shaking deck, transmission system, drive unit, slope adjustment mechanism, feed box, wash-water system, and supporting frame. Configuration may vary by model.

Confirm model dimensions and water requirements with LIPU before ordering.
Gemini Shaker Tables can be installed in mineral processing plants and testing facilities. Site configuration depends on feed preparation, water supply, concentrate collection, and the next process stage.
LIPU can provide model selection guidance and support for installation and commissioning. To discuss a suitable configuration, share your ore type, feed size, required capacity, and gravity separation targets.
What is a Gemini Shaker Table used for?
It separates mineral particles by gravity and deck motion, commonly to recover fine heavy minerals from prepared slurry.
Can it be used for gold recovery?
Yes. It can be used to concentrate gold-bearing feeds. Actual recovery depends on the ore, feed preparation, particle size, and operating settings.
Which materials can it process?
Typical applications include gold, tin, tantalum, tungsten, niobium, iron, and chromium minerals. Confirm suitability through material testing when feed properties are unknown.
What is the wash-water requirement?
The listed models require 12–38 L/min. The exact requirement depends on the selected model and operating conditions.
How do I choose a model?
Provide the ore type, feed size, target capacity, and required separation products. These details help determine whether a Gemini Shaker Table is suitable and which model to consider.
We provide a variety of mining and processing equipment, including feeders, rock crushers, grinders, classifying and screening machines, washing machines, gravity separators, flotation machines, magnetic separators, electric separators, dewatering equipment and laboratory mineral processing equipment.
