ABSTRACT:
A process for recovering hydrocarbons from a diatomite-type ore which comprises contacting the diatomite ore with a C.sub.4 -C.sub.10 alcohol and thereafter contacting the diatomite ore-alcohol mixture with an aqueous alkaline solution to separate a hydrocarbon-alcohol phase and an alkaline aqueous phase containing the stripped diatomite ore. Thereafter, the alcohol is distilled off from the hydrocarbon phase and recycled back into the initial process.
