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 …

On comparing the flotation rates for copper, generally the flotation rates were higher at 25 ℃ than at 60 ℃. The flotation rates of copper at both 25 and 60 ℃ are within a small range of 0.46–0.55 min −1. The highest copper flotation rate of 0.58 min −1 with R max = 86.27 % was observed for 25 HHL (IS = 0.412 M). Whilst copper was ...

As an effective measurement indicator of bubble stability, bubble size structure is believed to be closely related to flotation performance in copper rougher flotation. Moreover, reagent dosage has been shown to significantly influence the bubble size [17]. Frothers are known as flotation chemicals that have the greatest effect on bubble size.

The Jameson Cell The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.
