This paper reviews the applications of time of flight secondary ion mass spectrometry (TOF-SIMS) used for surface chemical analysis of mineral in the context of froth flotation. A wide range of applications are reviewed, including; interactions of reagents on the surface of mineral phases during flotation separation, determining the effects of various transferred ions from different minerals or...

The separation of graphites and cathode materials from spent lithium-ion batteries (LIBs) is essential to close the loop material used in LIBs. In this study, roasting characteristics LIB are carefully analyzed, effects on surface morphology elemental chemical states electrode fully investigated by thermogravimetric analysis, SEM-EDS, XPS explore roasting–flotation enhancement mechanism. Then, ...

Flotation is a conceptually simple operation; however, as multiphase process with inherent instability, it exhibits complex dynamics. One of the most efficient ways to increase flotation performance by implementing advanced controllers, such Model Predictive Control (MPC). This type controller very dependent on model that represents dynamics process. Although development one crucial parts in MP...

Froth flotation is a widely used method for the concentration of sulfide minerals. The structure superficial froth an indicator performance alongside with operational conditions in which this process carried out. aim study to explore how different that can be managed plant could directly influence observable characteristics froth. For purpose, image database was created using special laboratory...

Microalgae have great potential to be a feedstock for producing biofuel. One of the major impediments towards the industrial-scale manufacturing of biofuel from microalgae is the ineffective separation of microalgae from water. In this communication, we first carried out froth flotation tests to harvest freshwater microalgae (Chlorella sp. BR2) and marine microalgae (Tetraselmis sp. M8) from di...
