Weathered Kimberlite tailings of Panna Diamond Mines were characterised by DTA and XRD techniques. The XRD pattern shows the presence of serpentine, quartz, calcite, hematite, magnetite and anatase phases. DTA curve indicates first endothermic peak at 125-degrees-C due to dehydration of the mineral and second endo peak at 670-degrees-C due to dehydroxylation of serpentine closely followed by an exothermic peak at 810-degrees-C associated with the formation of forsterite. XRD and DTA studies of sulphuric acid leach residue of the Kimberlite shows the disappearance of serpentine phase with the appearance of CaSO4.2H2O phase. The product MgSO4.7H2O obtained after purification and crystallisation. From the optical emission spectroscopic analysis, the product was found to contain Ca, Fe and SiO2 as trace impurities. |
