ABSTRACT
In general, the purpose of the mineralization modeling is the advancement
of a mineral exploration project and ultimately, the extractive design of a
deposit, which is one of the
most important stages in mining engineering. Mineralization modeling is divided into two general
categories, superficial and deep modeling. In surface modeling, the aim is finding
abnormal locations in terms of mineralization at the study area, which is commonly
used in the early stages of exploration as one of the
means for locating exploratory boreholes. After drilling in the study area with
the aim of identifying mineralization and reserve estimation it is necessary to obtain deep
mineralization position and its geometric features,
using statistical and modeling methods. Using mathematical, statistical and
modeling methods, we can predict the position of iron mineralization in places
where drilling is not done and eventually reach a three-dimensional model of the mineral materials
underground. As a case study, the
deep information about the boreholes of the sheytoor mining area in Yazd province
of Iran was investigated. Iron mineralization was modeled as 2D cumulative model and 3D block
model, and the results were presented. Finally the geochemical threshold and the anomalous limit of iron element are
calculated by concentration-volume (C-V) fractal method in this deposit. Geochemical
threshold and the anomalous limit for Fe in this deposit are 24.7% and 34.3%
respectively.
