Third Instalment

The Shaking Table is very common in the mining industry in French Guiana. Recently, the Correia Mining Company demonstrated the Shaking Table at its operations in Olive Creek, Mazaruni. The table deck is made of fiberglass and is supported by a steel frame. It has a longitudinal adjustable tilt; one directional shaking movement and variable speed.
