Flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. Froth flotation is based on differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/liquid slurry.

2015-8-12 The UNDERFLOW is the pulp. When the pulp has had all the mineral extracted from it that the circuit was able to, and is discharged it is then called the flotation TAILINGS of the circuit. The flotation HEADS, the CONCENTRATE and the TAILINGS are the most important samples for the flotation operator that are taken. The assays from these will tell the operator the amount of valuable mineral coming in to the circuit.

2016-10-17 Flotation Circuits for Air-Lift and Pneumatic Cells. An air-lift machine can often be run as a rougher-cleaner cell, as in circuit No. 5 (Fig. 52), by taking a finished concentrate off the first few feet and returning the froth from the rest of the machine to the feed end. This method is also applicable to pneumatic cells, but its use is not common.

Flotation Circuit. Real-time density measurement can help to verify changes in the slurry from the grinding circuit to the flotation cells. The effect of flotation feed density on metallurgical performance has been investigated. Results of test work have shown that the pulp density affects key parameters of the flotation process in both the ...

This paper describes the design of a molybdenite flotation circuit using FLEET technology applied to kinetics data produced from laboratory flotation testing and distributed across theblocks of a mine plan using a geostatistical approach. The geostatistics assigned the statistical error that arises from having a limited amount of sample testing data to the kinetics estimates ofeach block of ore in the mine plan.

2012-2-7 Flotation is a complex process that is affected by a multitude of factors. These factors may be inherent in the circuit design, or in how the flotation plant is operated. The FloatStar suite of control modules utilises advanced process control to overcome design-related limitations and maximise circuit performance during operation.

2011-5-17 Performing a flotation rate test characterises the ore. The results of the test are used to calculate the flotation kinetics of metal or mineral and gangue under chosen test conditions. Change the test conditions and the kinetics change. The kinetics describes the behaviour of the ore and is a numerical representation of the ore’s mineralogical qualities and its metal – mineral – gangue

2009-8-27 1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
