Abstract
Sheytoor Iron Ore deposit is located in Yazd province of Iran (Bafq). The most abundant ore is magnetite, which can be seen in the form of mass and granular tissue in various forms of self-shaped, semi-self-shaped and amorphous. The main purpose of this study is to identify the geochemical relationship of phosphorus and sulfur elements and also three-dimensional modeling of mineralization of these elements in iron ore. In order to achieve the research goal, methods such as k-mean clustering technique, concentration-volume fractal as well as block modeling with kriging estimator and Inverse Distance Weighting (IDW) interpolator were used. The model of geochemical behavior of phosphorus and sulfur elements compared to iron is of great importance because these two elements are known as deleterious elements in mineral processing and steelmaking processes, which are the post-mining stages. Existence of geochemical model and identification of elements’ behavior towards each other play a key role in optimizing mining operations in order to achieve geometallurgical goals. The results of this study are the three-dimensional model of mineralization of iron, phosphorus and sulfur elements, separation of phosphorus and sulfur mineralization communities and also presenting the model of enrichment community of these two elements. All the results are in line with geometallurgical studies and can optimize the next steps by optimizing the mining process.

Summary
Iron is the most abundant metallic element in the earth’s crust after aluminum. The average abundance (Clark) of iron in the earth’s crust is 4.56%. Geochemical behavior is considered as an important tool in identifying the relationships between elements and how deposits are formed [10]. In two-dimensional (surface) studies, these communities can be identified by tools such as airborne geophysics and remote sensing (satellite image analysis) Each of these methods has already been used in several studies by researchers [20]-[25]. The purpose of investigating the geochemical behavior as well as three-dimensional modeling of phosphorus and sulfur elements in the present study is to optimize the mining process. Because these deleterious elements are along with iron ore in later stages such as processing and steelmaking. The production of the mine can be commensurate with the feed of the processing plant and the steelmaking process
