Summary on Grant Application Form |
|
In the minerals industry past studies on the breakage phenomena of materials report little or no information on the topography or surface structure of the resulting fragments. The topography holds key information on the mode of failure; here frozen onto the surfaces is a record of the tortuosity of the moving cracks. It is the interaction of these cracks that formed the fragments.This project will develop methodologies to describe the topography of fragmented materials through the exploitation of three inter-related aspects of applied fractal geometry (ie the boundary fractal, the fragmentation fractal and the surface fractal). Automated image analysis techniques will be developed to rapidly assess the fragmentation and boundary fractals from populations of fragments. Through single particle breakage tests we will assess the use of the fragmentation fractal as a definitive measure of the degree of fragmentation for a range of rock and ore types. The relationship between the surface fractal and the boundary fractal of fragments produced from single particle breakage tests will be assessed. The validity of these methodologies will be tested to predict product particle size distributions from comminution events using knowledge of the surface fractal dimension and the fracture toughness index of a material.
