MODEL BASED PREDICTIVE CONTROL OF A ROUGHER FLOTATION CIRCUIT CONSIDERING GRADE ESTIMATION IN INTERMEDIATE CELLS

Rougher flotation is the first stage in the concentration of low grade minerals and its goal is to maximize recovery, keeping the concentrate grade within acceptable ranges. Good control at this stage is important because it directly affects the performance of the concentrate operation, and small increases of even 0.5% recovery in rougher flotation result in significant economic benefit [8].
