Gravity Separation Lec 8 Gravity Separation Separation by Jigs Separation by Spiral Concentrators Separation by Shaking Tables wet shaking tables The particle separation is assisted by the backwards and forwards motion (stroke) of the table, the tilt (both longitudinally and laterally), wash water applied along the length of the table, and riffles. Operating variables include: Tilt angle Slope angle Splitter positions Wash water Stroke length Feed rate and density Riffle height Dry shaking tables Dry shaking tables or air tables have specialized dry gravity separation applications such as fine quartz and zircon. Operating variables include: Tilt angle Splitter positions Fan dampers (for air flow) Stroke length Feed rate
