Abstract
Detection of mineralized zones based on ores and gangues is important for mine planning and excavation operation. Major goal of this research is determination of zones based on ores and gangues by combination of fractal and factor analysis in Chah Gaz iron ore (Central Iran). Concentration-Volume (C-V) fractal method was carried out for Fe and S which indicates the main mineralized zones consist of Fe, S and P values ≥57%, ≤0.4% and ≤0.3%, respectively. Factor analysis categorized variables in two groups including factor 1 (F1) and factor 2 (F2) for ore and gangue, respectively. The C-V fractal modeling on the derived factors shows four zones for the F1 and F2. Based on the correlation among results of fractal modeling on the elements and factors, first and second zones of F1 are proper for exploitation. Furthermore, the last and first zones of F1 and F2 can be assumed as main waste for mining excavation.
