Factor 3: Water Flow. The effect of water flow on mining shake tables is a crucial but often overlooked aspect of the operation. When the water flow rate is too high, it results in inefficient mineral separation, causing the minerals to be carried away by the excess water instead of collecting on the table. Conversely, more water flow can lead ...
