Geostatistical modelling for sulfur element in ghorabi iron ore mine area, bahariya Oasis, Egypt

Abstract EN

Sulfuris a concern in Ghorabi iron oreand it is an unwantedcomponent when the ore is chargedinto a blast furnace.

The goal of this paper aims to track thesulfur contentin Ghorabi iron ore by using geostatistical modelling.

Geologically, the ore is splitinto fourdistinct zones.

The experimental variograms were created tohighlight the spatial variability of sulfur element within the deposit.

The experimental variogramswere fitted with Gaussian, linear and exponentialvariogram models.

Finally, the appropriate fitted models were utilized to create a distribution mapsfor the four separated zones using the ordinary kriging and indicator kriging in 0.7% cut-offs.
