Batch and column leaching studies were carried out on oil shale mined from the Rundle resource, Queensland, and retorted by the Lurgi-Ruhrgas process. The kinetics of dissolution of the major leachable components in the shale (Ca, Mg, Na, K, Cl, SO4 and alkalinity) were established. Material not associated with CaSO4 salts or carbonates was found to dissolve rapidly when extra-particle mass transfer effects were minimised. Ca and SO4 dissolved from CaSO4 salts at a rate which was dependent on the solution concentrations of these species. It was apparent from the eluted leachate concentrations that chemical reactions and equilibria dominate the column leaching behaviour of the major components. |
