thesisThis thesis deals with the procedures and considerations of High Resolution X-ray Micro Tomography (HRXMT) to describe the internal structure and composition of multiphase mineral particles using XRadia's Micro XCT 400. Issues such as sampling statistics, sample preparation, scan conditions adjustment, image evaluation, and data analysis are considered. Mineral characterization using Computed Tomography (CT) standards is also discussed with the procedure of making a CT standard and comparison of HRXMT results and automated analysis of polished sections (QEMSCAN) results. In order to record and establish scan conditions, a database is provided. The use of XMuDat is discussed step by step for the user to easily evaluate the mass attenuation coefficient relationship of a mineral sample. The operating procedures of the XRadia Micro XCT 400 system are also set for a new user to be able to understand and operate the system for a sample scan. Several applications using HRXMT are also discussed. First, a few oil shale samples have been investigated to acquire high resolution internal structure images. Second, the methodology for rapid radiographic scans to identify heavy metal mineral rich regions in low grade ores is developed as an initial attempt to effectively link mine to mill. Finally, scans and analysis of teeth are presented to define internal structures in three dimensional images using CT Standards
