Abstract

In this paper, the mineralogical and physical characterisation of Jarosite, Clay and Fly ash was investigated. The XRD results revealed the presence of alacranite (AsS) and jarosite (K (Fe₃(SO₄)₂(OH)₆)) mineral phases in the hazardous jarosite, while clay was composed of Kaolinite (Al₂Si₂O₅ (OH)₄), Anatase (TiO₂) and Quartz (SiO₂). Furthermore, Fly ash contained phases Mullite (Al₄.₆₄Si_1.36O_9.68), Quartz (SiO₂) and Calcium oxide silicate chloride (Ca₂O₂Si₃Cl₂). The XRF results confirmed that the Fly ash used is in class F (Hazardous material). There were hazardous elements such as As and Pb in the Jarosite sample. Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (SEM/EDS) revealed differences in surfaces morphology and EDS results were in agreement with the XRF analysis. The densities of the samples were 3.13 g/cm³, 2.67 g/cm³ and 2.21 g/cm³ for Jarosite, clay and Fly ash respectively. There was an increase in density with the increase of the percentage of Jarosite in the mixture whereas a decrease in density was noticed with the increase of Fly ash percentage in the mixture of Jarosite and clay.
