Abstract
Raw oil shale is retorted to liberate an effluent product stream. Ammonia is withdrawn from the product stream and reacted to produce ammonium nitrate. Shale oil is separated from the product stream and mixed with 90% to 98% by weight ammonium nitrate to produce explosives. The shale oil can be whole shale oil or heavy shale oil containing from 0.1% to 65% by weight oil shale dust. The ammonium nitrate is preferably in the form of explosive grade ammonium nitrate prills. The shale oil is preferably heated before being mixed with the ammonium nitrate to make the shale oil more blendable.
