Investigation of P2O5% and Fe2O3% Geostatistically within Abu Tartour Phosphate Deposit, Western Desert, Egypt

Geostatistical techniques play an important role to study the mineralization behavior within the ore deposits. When preparing the phosphate deposits for marketing, we try to minimize the iron content due to the harmful effect of this element on the physical and mechanical properties of superphosphate and phosphoric acid. One of the biggest problems in Abu Tartour phosphate deposits, Western Desert, Egypt is the high iron content within apatite grains. The received data are analyzed statistically to show the distribution of P2O5% and Fe2O3% at Abu Tartour area. Also, experimental variograms have been constructed for P2O5% and Fe2O3% of phosphate deposits through the studied area to reflect different variogram models. After fitting the variogram to suitable variogram model, kriged models are established for each variable.
