Flotation stabilization and optimization - SAIMM

stabilization and optimization of flotation circuits. Flotation is a process with many inputs and complex interactions. The modelling of flotation is reviewed by Mathe et al.1 Some current modelling techniques are explained by Manlapig and Franzidis2, who account for the effects of ‘true’ flotation, entrainment and froth recovery. Edwards and Flintoff3 were of the opinion that mathematical ...

Automated Flotation Optimization Using Froth Cameras

An optimization routine for a flotation circuit must first begin with mastering level control even in the presence of disruptions (waves, etc). Ideally, a level control system would adjust downstream levels preemptively to account any upstream disruptions before the effects of the disruptions propagate downstream. The level for each cell is a mathematical function of the level and dart valve ...

Flotation Plant Optimization

A mathematical model was developed for the grinding and flotation section of Union Carbide’s Bishop mill and this model was used to indicate how variations in grind, retention time, and calcite and fluorite content effects the mill capacity, tungsten units produced, and the grade and recovery of the scheelite concentrate. A model such as this is a starting point in determining the economic ...

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited.
