This study aims to demonstrate the relationship between the major oxides and mineralogy, as well as the effect of clay minerals in increasing the distribution of heavy metals in the soil of present study.
22 samples were collected from the refinery and nearby area. All samples were analyzed to determine the concentrations of heavy metals by atomic absorption spectrophotometer. The results showed that the concentration of heavy metals (Cd, Pb, Cr, Ni, Fe, Mn, Zn, Cu) the three samples with the highest concentration of heavy metals and the three lowest samples were identified to conduct an analysis of the major oxides using an XRF. The results showed the highest percentage of silica oxide and calcium oxide in comparison. Other oxides such as SO3, Al2O3, MgO, Na2O, Fe2O3, K2O. The results of clay and non-clay minerals, which were conducted for the three samples with the highest concentration of heavy metals, as well as for the three samples with the lowest concentration of heavy metals, using an XRD device, showed most common non-clay minerals were Quartz, gypsum and calcite, the non-clay minerals with lower percentages such Albite, Dolomite, Halite, Rutile, small percentages of the clay minerals were represented by chlorite, Palygorskite and Illite.
The results of the study showed that an increase in silica oxide indicates the presence of quartz, and an increase in calcium oxide indicates the presence of carbonate minerals, especially calcite and dolomite. Since the percentage of clay minerals is small, it cannot be considered a factor in the distribution of heavy metals.
