Abstract:The separation of water from iron ore tailings has become one of the most important issues for mining companies, due to the decommissioning dam duty. This paper presents the electrokinetic separation method, as well as an automatic drive circuit for the system, to optimize the dewatering process. The circuit is based on a voltage regulator controlled via PWM (Pulse Width Modulation) and is used to automatically apply an electrical voltage gradient to an electrokinetic cell, aiming for constant dewatering.
