Microwave enhanced processing of ores - Nottingham ePrints

Recent research developments have suggested that microwave assisted comminution could provide a step change in ore processing. This is based on the fact that microwave-absorbent phases within a multi-mineral ore can be selectively heated by microwave energy hence inducing internal stresses that create fracture. A detailed review of existing literature revealed that little or no information is ...

This is the first report describing a new technology where hydrophobic nanoparticles adsorb onto much larger, hydrophilic mineral particle surfaces to facilitate attachment to air bubbles in flotation. The adsorption of 46 nm cationic polystyrene nanoparticles onto 43 μm diameter glass beads, a mineral model, facilitates virtually complete removal of the beads by flotation.

Coarse and Fine Particle Flotation Recovery

Coarse and Fine Particle Flotation Recovery ... Coarse VS Fine Flotation. It is a very natural assumption upon the part of many people that, the finer the particles are, the easier it is to float them. This assumption has rested on two grounds: Finer particles in a given ore are more extensively liberated.
