The mineral matrix in Green River oil shale was partially removed by treatment with dilute HCI. The major ionic species in the solution from acid treatment (AT) were identified as NaC, A13+, Fe'+, Mg\*', and Ca\*+. The ion yields expected from reaction stochiometry, gravimetric analyses and comparis
Iron phases in raw and retorted shales have been studied from the TOSCO II, Paraho, and Lawrence Livermore Laboratory (LLL) 125 kg retorting processes by MGssbauer effect spectroscopy. Using the Mijssbauer effect, changes in the iron mineralogy during retorting were monitored. Results show that the
