How to maximize ore and grade recovery through

2020-3-6  Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed. It is possible that some banks of flotation cells might not be recovering ore at their maximum levels due to air flow, feed, mechanical, hydraulic, reagent imbalances.

An Overview of Calcite Recovery by Flotation

2020-9-23  There are few studies on sulphide flotation by primary di-amines in literature; Kydros et al. (1993) showed that pyrite can be floated with cetyltrimethylammonium bromide (CTMAB) resulting in maximum recoveries at pH 3–4 and decreasing recoveries with increasing pH although floating at pH 12.

2015-3-31  The overall mineral recovery (R) is the sum of the recovery by flotation (R float) and the recovery by entrainment (R ent). Water and suspended solids enter the froth in the wake of the air bubbles. Coarse particles are usually not present just below the froth due to sedimentation, and hence recovery by entrainment decreases as particle size increases.
