Predicting Flotation Recovery
Predicting Flotation Recovery. Unfortunately, many milling engineers rely rather heavily on percent recovery as a strict measure of a concentrator's relative performance. The fallacy of this reasoning is not difficult to see since, by definition, percent recovery is a function of feed assay, tails, and concentrate grade.

Two levels of a four-factorial design were used for the modeling and optimization of these flotation reagents. The high correlation coefficients of the model equations for the grade (R 2 = 0.89) and recovery (R 2 = 0.96) indicated that the predicted values were in good coordination with the observed values.

To increase the effective size of ultrafine particles for flotation, flocculants can be used to aggregate the particles, thereby improving flotation (Forbes, 2011). The ultimate objective is to create aggregates (or flocs) that would both increase the effective particle size but will also create hydrophobic surfaces suitable for flotation.
