Application Examples

The Gemini Shaking Table is versatile and can be used in various applications, including:

  1. Gold and Precious Metal Recovery:
    • Efficiently recovers gold, silver, platinum, and other precious metals from ore, concentrates, and tailings.
  2. Mineral Processing and Testing:
    • Used in laboratories for small-scale mineral separation studies to evaluate processing methods.
  3. Fine Particle Separation:
    • Ideal for separating fine particles of heavy minerals from lighter gangue materials.
  4. Tailings Reprocessing:
    • Recovers valuable minerals from tailings, reducing environmental impact and waste.
  5. Industrial Applications:
    • Beneficiates rare earth elements, tungsten, or other high-value heavy minerals in specialized industries.

Operating Principle

The Gemini Shaking Table operates on the principle of gravity separation combined with vibration to achieve precise mineral concentration. The process involves the following steps:

  1. Feed Material Introduction:
    • Slurry containing a mixture of fine particles is fed onto the table’s inclined surface.
  2. Vibration and Flow Dynamics:
    • The table vibrates at a controlled frequency, causing materials to stratify based on their specific gravity.
    • Water flows across the table surface, assisting in the separation of particles by washing lighter materials away.
  3. Particle Separation:
    • Heavier particles (e.g., gold, heavy minerals) are trapped in the grooves of the table’s surface and move to the higher end of the table.
    • Lighter particles are carried by water and vibration to the lower end of the table, exiting as tailings.
  4. Concentrate Collection:
    • The concentrated heavy mineral fraction is collected from the discharge point at the high end of the table.
    • Tailings are discharged separately for disposal or further processing.

Key Factors for Optimal Operation:

  • Proper adjustment of the table’s inclination, vibration frequency, and water flow rate is critical to achieving effective separation.
  • Feed material should be pre-classified to the recommended particle size range for best results.

Working Principle

Shaking tables operate on the principle of moving material across an oscillating surface at a specific speed and amplitude. The table surface continuously shakes the material along with water, creating a gravity concentration process. Through this oscillating motion, heavier minerals migrate upward along the table surface, while lighter particles move downward. This movement enables mineral separation and concentration into distinct layers based on density, effectively stratifying the material according to specific gravity.
