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...

Understanding Surface Forces and Interaction Mechanisms in Mineral Flotation by Atomic Force Microscopy
DownloadFall 2019
Bubble-particle interactions are ubiquitous and crucial to mineral fotation. The bubble-particle attachment process is mainly governed by three surface forces: van der Waals (vdW), electrical double-layer (EDL), and hydrophobic (HB) forces. Atomic Force Microscopy (AFM) has become the most...
