Method for treating shale |
摘要 |
A method for producing a kerogen concentrate from oil shale comprises treating shale with an aqueous caustic treating solution to produce a shale product of substantially transformed mineral content, and then treating the shale product with an aqueous acid solution to produce a kerogen concentrate. The acid solution extracts minerals from the shale product to lower the ash content of the kerogen concentrate. A spent acid solution containing the extracted minerals can be treated to recover minerals therefrom.
