This article presents recent developments in the field of mineralogical analyses based on X-ray computer tomography (CT). The analysis of the data obtained indicates a good repeatability of measurements, and, consequently, the possibility of using the CT method for the purpose of studying rocks during their enrichment, as well as predicting the rock behavior in the process of disintegration. Porosity parameters, particularly void density, according to CT data correlate with rock strength whereas the total porosity, which is determined from the values of mineral density, enables only an indirect estimation of the rock strength and provides no information about size, shape of pores, their connectivity and spatial orientation. |
