Particle Processing II

Description

This course is concerned with advanced topics in particle processing, especially in relation to the coal and minerals industries. Following a general introduction to mineral processing, particle characterisation and particle-fluid interactions, the course provides a flux curve treatment of gravity separation, flotation and thickening circuits. Students gain a unique and fundamental appreciation of the governing principles.

Content

  • Introduction
  • Broad appreciation of the technology employed in the coal and minerals industries to process, recover and concentrate particles of value.
  • Particle characterisation
  • Applications of Gravity Separation
  • Sedimentation, solids flux theory of thickening
  • Segregation and Dispersion in Fluidization
  • Particle Fractionation, grade recovery / washability
  • Application of theory to gravity concentration devices (e.g. dense medium, cyclones, spirals, fluidized bed systems and enhanced gravity).
  • Bubble-particle interactions
  • Drift flux theory, as applied to flotation
  • Hydrodynamics of two-phase systems
  • Introduction to the Kinetics & Chemistry of flotation
  • Appreciation of how these principles affect the standard plant designs in coal and mineral processing circuits.
