Froth Flotation of Minerals Simulation

Froth Flotation of Minerals Simulation GRADE LEVEL: 6-8 INTRODUCTION: Froth flotation is the separation of valuable minerals from non-valuable minerals in ore using the three major phases of matter (solid, liquid and gas). Flotation is a common process for recovering copper, iron, molybdenum, zinc, and many other metals in their mineral forms

[PDF] Managing clay minerals in froth flotation—A critical review

ABSTRACT Clay minerals are widely present in various ore deposits as gangue minerals. The processing of high-clay-content ores is becoming a significant challenge for the mining industry owing to the poor flotation performance caused by the presence of clay minerals. Different types of clay minerals are typically present in ore bodies, and they cause several …

Frothers in flotation: A review of performance and function in the

The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by flotation takes advantage of the wettability …

A Review on Froth Washing in Flotation

In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced into or on top of the …

Selective Aggregation of Hydrophilic Gangue Minerals in Froth Flotation

In a highly dispersed flotation pulp, ultrafine hydrophilic minerals can entrain into froth products even though they may be perfectly hydrophilic. Therefore, effective depression of the hydrophilic minerals in froth flotation relies not only on rendering the minerals hydrophilic, but also on proper particle size control. In this paper, it will be shown that several depressants in …

(PDF) Impact of Clay Minerals on Froth Stability

The reactivity of clay minerals and variety of these reactions are greater than any other known colloidal material. While it is acknowledged that clay minerals can cause problems in mineral flotation, the literature contains conflicting evidence, particularly with respect to the effect of clays on froth stability.

A review of froth flotation control

The two higher tiers of flotation control are advanced flotation control (AFC) and optimising flotation control (OFC). AFC involves the rejection of the effects from input disturbances to the process (e.g. a change in feed grade) and maintaining performance parameters — grade and recovery (although care should be taken when defining recovery; in a dynamic situation …
