A large amount of carbon dust is generated in the process aluminum smelting by molten salt electrolysis. The solid hazardous waste but contains a quantity recyclable components such as and fluoride. How to recycle more effectively challenge electrolysis field. In this study, X-ray diffraction, scanning electron microscope, other methods were used analyze phase composition electrolytic dust. eff...

It is well documented that the use of grinding aids (GAs) can reduce milling energy consumption. However, impact GAs on downstream processes must be addressed in view complex such as froth flotation separation. This study investigates effects polyacrylic-based (Zalta™ GR20-587: AAG) performance and quartz from magnetite. Various AAG dosages conditions were examined. The results showed lower con...

Interactions between particles and bubbles have been cornerstone for the successful applications of froth flotation to beneficiations minerals or coal. Particle-bubble interactions are highly physio-chemical processes on basis surface science hydrodynamics. Though these two aspects deeply interwoven, we focus discussions effects turbulence bubbles, i.e., collision, attachment detachment. It has...

Controlling bubble motion or passively bursting bubbles using solid interfaces is advantageous in numerous industrial applications including flotation, catalysis, electrochemical processes, and microfluidics. Current research has explored the formation, dissolution, pinning, rupturing of on different surfaces. However, ability to tune control rate not yet achieved. Scaling down surface-induced ...

Sulfomethylation of radiata pine kraft lignin was performed using formaldehyde and sodium sulfite under alkaline conditions to determine its potential as a mineral depressant for the separation molybdenite chalcopyrite by froth flotation. Optimal sulfomethylation reaction were 20% (w/w) Na2SO3 at 130 °C 4.2 h, which resulted in with sulfonate content 2.2 mmol/g. Microflotation assays showed tha...
