Abstract: Soil samples were analysed to determine the heavy metals (pH, Cd, Zn, Ar, Cr, Cu, Pb, Hg, Fe and Ni) at Kataeregi mining site, Niger State, Nigeria. Ten soil samples were collected from four soil pits and control site were collected 100 m away from mining site. The results of the analysed soil samples are as follows: Soil pH values of various locations ranged from 6.08 to 8.12 which is indicative of moderately alkaline, Ar values ranged from 4.23 mg/kg to 12.05 mg/kg, Ni values ranged between 4.00 mg/kg and 70.0 mg/kg and is above the standard set for agricultural and human health, Fe ranged from 0.72 mg/kg to 16.03 mg/kg, Hg values ranged between 0.11 and 1.01, Cd values ranged from 4.76 mg/kg to 9.32 mg/kg which is indicative of high concentration of chemical parameters and Cr ranged between 9.89 mg/kg and 27.00 mg/kg. Cu values ranged from 99.78 mg/kg to 111.9 mg/kg while Pb values ranged between 1.0 mg/kg and 6.07 mg/kg and Zn values ranged from 9.91 mg/kg to 13.0 mg/kg. It is observed that concentrations of Ar, Ni, Hg, Cd and Cr are above the CSQG standard while that of Fe is found to be below the standard set by CSQG & WHO and Cu, Pb, and Zn are within the permissible range.

Abstract: The process of using mining rock waste as raw material to synthesis zeolite species is a viable alternative. Such process is minimizing serious impact of mining wastes on the environment and solving environmental problems such as water purification. In the present study, faujasite (NaX) and sodalite – cancrinite (sod-can) zeolites were successfully synthesized by hydrothermal crystallization using green siltstone, mudstone and black shale of mining rock wastes from Abu Tartur phosphate mine, western desert, Egypt. The raw materials as well as synthesized zeolites were characterized by means of X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), Thermogravimetry (TG), Differential Thermal Analysis (DTA) and Brunauer–Emmett–Teller (BET). Raw material (black shale) and synthesized zeolites (Na-X) faujasite were examined as heavy metal (Fe and Mn) adsorbent from aqueous solution. The results show that Na-X faujasite is very faster and higher in the up taking of Fe2+ and Mn2+ ions relative to the black shale absorbent or even the synthesized sodalite-cancrinite. Fe2+ and Mn2+ adsorption onto black shale absorbent and synthesized faujasite followed Langmuir isotherm, however, Freundlich isotherm model is accepted in the case of sodalite-cancrinite adsorbent. The adsorption kinetics of Fe2+ and Mn2+ onto the studied samples follow pseudo-second order model indicating chemical interaction (chemisorption) adsorption process.
