Successful flotation relies on several sub-processes, such as promoting the attachment of certain sizes of particles to bubbles while preventing the attachment of others. Therefore, it is important to advance our knowledge about the particle attachment process, particularly, when different particle sizes are considered. Here we use our in-house setup to study:

  • The effect of ultrafine particles on the attachment rate of fine particles.
  • The effect of various parameters e.g., particles hydrophobicity on the packing density of the particles.
Experimental methods/techniques:
  • Image analysis
  • Particle size analysis techniques such as laser diffraction and dynamic light scattering

These experimental methods and the topic of particles at interfaces can prepare you for a variety of jobs after graduation, as these concepts are widely applicable in various fields such as mineral processing, recycling, pharmaceuticals, cosmetics, painting, and so on.
