Abstract
A process for the production and the conversion of shale kerogen to produce shale oil. The process includes grinding crushed shale into a first product and treating the first product with a first collector. The treated first product is introduced into a first flotation zone in order to recover liberated kerogen. Subsequently, the recovered liberated kerogen is ground into a second product which is treated with a second collector. The treated second product is introduced into a second flotation zone in order to recover clean kerogen. The recovered clean kerogen is mixed with a liquid means to form a pumpable kerogen paste which is subsequently introduced into a reaction zone in order to convert the kerogen in the pumpable kerogen paste into a hydrocarbon liquid that is subsequently removed from the reaction zone.
