Disclosed is an improved method for the retorting of oil shale comprising passing feed comprising shale to a contacting zone wherein the feed oil shale is contacted with heat transfer medium to heat said shale to retorting temperature. Retorting of the feed oil shale is substantially effected to fluid material having heating value and forming partially spent oil shale comprising inorganic and carbonaceous material. At least a portion of the partially spent oil shale is passed to a combustion zone wherein the partially spent oil shale is contacted with oxidizing gas comprising oxygen to substantially combust carbonaceous material and forming spent oil shale. At least a portion of the spent shale is passed to a cooling zone to remove heat from the spent shale and at least a portion the spent shale from the cooling zone is recycled to the contacting zone.
