Abstract

Modeling of nickel laterite resources is intended to determine the distribution of resources represented in the form of block models. The results of resource modeling indicate the shape and distribution of mineral deposits which can facilitate the mining process and can predict mining boundaries referring to the results of resource modeling. The purpose of this study was to determine the thickness of the saprolite zone layer and the distribution direction of nickel laterite based on drill point data. The data used in the laterite nickel resource modeling are exploration drill data, drill coordinates, and exploration grade classification. Data processing and analysis methods apply block modeling and the variogram method to determine the distribution direction of nickel resources. Based on the results of the cross-section profiles in Section 1 to Section 7, the average thickness of saprolite is 6,605 m, and the block model layer of saprolite which shows high levels of red color (Ni 1.9 - so on) is the most in the north, pink color (Ni 1.5-1.89) is in the north direction before the Ni 1.9 level above, the green color (Ni 1.3-1.49) is in the east and south.

Abstract

Iron sand is one of the industrial minerals. Iron sand ini Indonesia is still limited to being used as a raw material for cement factories in the manufacture of concrete. Iron is given the symbol (Fe) in the periodic table's chemical element. The purpose of this study was to determine the mineral properties of iron sand and the chemical characteristics of iron sand. The research location is in Jeneponto, Jeneponto is a district in the province of South Sulawesi, Indonesia. The stages of the sampling method are carried out by measuring the distance of each sample hole. From one point to another, within 10 meters with a depth of 30cm each from the surface after that the sample that has been taken is then dried. This research method uses XRD and XRF analysis methods. From the results of the why XRD analysis, it was found that 2 minerals carrying iron sand, including Magnetite and Hematite with the percentage content of these minerals, are. Magnetite mineral (Fe3O4) 40,0% and Hematite mineral (Fe2O3) 37,7%. From the results of XRF analysis shows that the chemical composition contained in Fe2O3 minerals contains oxide and hydroxide elements Fe, O, Oxide is a chemicali compound that contains at leasti one oxygen atom and at least one other element.
