✦ Synopsis

An ultrasonic field was found to enhance the rate of mineral dissolution from Green River oil shale matrix when treated with dilute HCI. This effect was most pronounced forcoarse particlesand minimal for finely pulverized shale. Data comparing the behaviour in an ultrasonic field with control specimens are presented in terms of gas evolution profiles, ion concentrations and gravimetric analyses.

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
