Abstract
A method is described of concentrating oil shale by flotation. It is characterized by grinding the shale to a grain size which, roughly speaking, is less than 0.06 mm. and more conveniently should be less than 0.05 mm., and followed by flotation. During the process the brown foam formed is separated as concentrate, while the black-brown to all-black foam is separated as a middle product, ground fine again, and thereafter floated once more. The patent contains five additional claims.
