The Solution
Spartan Controls implemented the SpartanPRO™ Thickener APC to automatically optimize underflow pumping rates while continuously monitoring key constraints, including rake torque, line velocities, and pumping limits.
Using a model predictive control (MPC) strategy, the solution managed slow process dynamics and multiple constraints while maximizing underflow density. A low‑rate recirculation line was also leveraged to further reduce tailings losses.
