To overcome the challenges of low recovery of fine particles in flotation processes, designing a cavitating device that can enhance the recovery has been a major topic of study. In the design of a cavitating device, the bubble/bubble interactions, bubble response to the change of local pressure,...
Descriptor-Based Explorations on Flotation of Metal Sulfides Using Density Functional Theory CalculationsDownload
Descriptor-based computational studies hold great promise for a more efficient optimization strategy for froth flotation of metal sulfides. To achieve this, fundamental insights into the ligand–metal sulfide interaction mechanism and identification of an effective descriptor possessing a...
In this study, the flotation behaviors of chalcopyrite and pyrite single and mixed minerals in Milli-Q water, NaCl solution, and sea water were investigated. The performance of different collectors was evaluated. Collectorless flotation was also studied under potentiostatic control to explore the...
The presence of hydrodynamically generated air bubbles has been observed to enhance fine particle flotation in a high intensity agitation (HIA) flotation cell. In this study, the cavitation in an HIA cell, used in our laboratory, is studied by hydrodynamic computational fluid dynamics. Different...
In nature, the molybdenite ores are frequently associated with copper sulfide minerals such as chalcopyrite, and the flotation separation of copper-molybdenum (Cu-Mo) sulfides largely relies on the use of toxic and hazardous depressants such as cyanides, Na2S/NaHS. It is desired to replace these...
Due to challenges faced by the Wabush mine, the separation of pyrolusite and hematite using froth flotation was investigated. Using sodium oleate as a collector, micro-scale flotation testing identified conditions for selective separation of pyrolusite and hematite. When applied to Wabush iron...
Canada has the largest known reserve of oil in the world in the form of oil sands: an estimated 1.7 to 2.5 trillion barrels of oil are deposited in combination of the sand, water and clay. The presented research is devoted to bubble-solid surface interaction, which is one of the critical areas...
