Mineral Particle - an overview | ScienceDirect Topics

Mineral particle attachment to air bubbles is the basis of the froth flotation process. A three-phase system is created, by various mechanisms, in which the following three interfacial tensions exert governing effects: (1) the gas–solid tension, (2) the solid–liquid tension, and (3) the gas–liquid tension, i.e., flotation being a quite ...

Particle Size Analysis - an overview | ScienceDirect Topics

The common methods for fine sieving are machine, wet, hand and air-jet sieving. Wet-sieving is recommended for material originally suspended in a liquid and is necessary for powders which form aggregates when dry-sieved. In such tests the stack of sieves is filled with liquid and the sample is fed to the top sieve.
