Shaking tables can recover up to 90% of the gold present in material between the sizes of 3 mm and 50 pm, however they are most efficient when processing material in this size range. They can also be used for finer material, but their effectiveness will be lower. ... Studies that frequently assessed various parameters like frequency, amplitude ...

The major advantage of shaking tables is the fact that separation can be observed in real-time. This enables changes and allows adjustments to be made, hence improving the next separation process. The disadvantage of using a shaking table is the water consumption. Water is increasingly becoming a rare and expensive commodity.
