Gravity concentration systems – for enhanced productivity
The CVD Concentrator uses similar principles of mineral separation and recovery to that of the Knelson Semi-Continuous Concentrator. The CVD technology differs by discharging a continuous stream of concentrate while simultaneously processing fresh feed, whereas the other units must be stopped intermittently to remove the high-grade concentrate.
