| 4. | Description | Abstract |
A study was carried out on leaching of Nigerian kaolin ore by Oxalic acid (C2H2O4.2H2O). The raw kaolin ore from Share, North central Nigeria was characterised by EDXRF (X-ray fluorescence) and major constituents were SiO2, Al2O3, and minor amounts of K2O, Na2O, CaO, TiO2, along with colour-imparting Fe2O3 and MnO that need to be remove to upgrade the kaolin suitability for industrial usages. The effects of parameters such as C2H2O4 concentration, temperature, and particle size were investigated. Under the standard leaching conditions of −75+63 μm particle size, 75 °C and 0.15 mol/L C2H2O4, about 78.5% of kaolin ore was reacted within 120 minutes. Comparison of the EDX analysis of the raw and leached kaolin showed removal efficiency of 97.1% for the iron at optimal leaching conditions. Energy of activation of 17.65 kJ/mol was obtained in the study supports the proposed diffusion control mechanism for the dissolution process. |
