2-1TECHNICAL NOTES 2PARTICLE POPULATIONS AND distribution IntroductionThe behavior of ore dressing equipment depends on the nature of the individual particles that are processed. Thenumber of particles involved is very large indeed and it would be quite impossible to base computational procedureson any method that required a detailed description of the behavior of each PARTICLE . The complexity of such procedureswould mean that any useful or meaningful models would be entirely out of the question. But the characteristics ofindividual particles do have to be taken into account and useful models cannot be developed if these are to be basedsimply on average properties of all the particles in the particles differ from each other in many respects: the differences that are of interest in ore dressingoperations are those physical properties that influence the behavior of a PARTICLE when subject to treatment in any oredressing equipment.
