Special Issue Information

Mineral flotation has remained one of the primary methods of mineral beneficiation for over a century. However, the minerals industry and flotation practice are facing technical challenges like never before. At the same time, fundamental developments within the field of mineral flotation have been steadily progressing.

This Special Issue titled “Mineral Flotation—Fundamentals for Improved Application” aims to gauge how recent developments in the fundamental understanding of mineral flotation can generate better outcomes for industrial application. This Special Issue will provide an opportunity for researchers to share and discuss new ways in which their research can affect future change in mineral flotation practice.

Authors are invited to submit original research articles, review articles, and significant preliminary communications covering a range of topics and scopes. The articles could focus on any aspect of mineral flotation, as long as they demonstrate the applicability of fundamental knowledge to plant practice in the short, medium or long term. Topics could include (but are not limited to):

  • Development of novel flotation reagents
  • Surface and colloid chemistry effects on mineral flotation
  • Novel instrumentation and analysis techniques
  • Mineral surface and geochemistry
  • Process modeling
  • Hydrodynamics and their effect on equipment design
  • Flow rheology
  • Novel flotation technologies

Bubble size measurement is a vital part of flotation system analysis and diagnostics. This work evaluates a commercial camera probe as a novel method for in situ bubble size measurement. This device is compared to the conventional Anglo Platinum Bubble Sizer (Stone ThreeTM). It was found that, in laboratory applications, the in situ bubble size analysis technology appears to be a more user-friendly and reliable option for determining bubble size in flotation, whereas the Anglo Platinum Bubble Sizer is more applicable for full scale industrial work. This probe was then used to conduct a rigorous comparison of the behavior of different frother chemistries at a variety of background solution ionic strength conditions. The critical coalescence concentrations and the minimum Sauter mean bubble diameters were determined. Five frothers were compared in terms of their ability to reduce bubble size and sensitivity to salinity. In order to adjust plant recipe and control strategy accordingly, it is recommended that the plant would need to use less frother during periods of the high salinity of process water to achieve the minimum Sauter mean bubble size.
