TRACE ELEMENTS MINERAL TRANSFORMATIONS ASSOCIATED WITH HYDRATION AND RECARBONATION OF RETORTED OIL SHALE

A laboratory study was conducted to evaluate the influence of hydration and recarbonation on the solid phase distribution of trace elements in retorted oil shale. The oil shale samples were retorted by the Paraho direct heating process and equilibrated with deionized distilled water under controlled carbon dioxide conditions. A sequential extraction technique was then used to fractionate trace elements into soluble. KNO3 extractable, N2O extractable, and residual phases. The chemical fractions present in retorted oil shale and hydrated and recarbonated retorted oil shale were compared to identify trace element mineralogical changes that may occur n retorted oil shale disposal environments.
