Abstract

518,955. Concentrating oil shales. VISURA TREUHAND-GES. Oct. 7, 1938, Nos. 29081 and 29082. Convention dates. Oct. 9, 1937, and March 18, 1938. [Class 82 (ii)] The organic matter content of oil shales is concentrated by froth flotation using a frothing agent containing no fats or paraffin or mineral oils, such as amyl alcohol, wood tar, or shale tar, and an alkaline depressant such as water glass. The pulp is preferably thick, for example with a water-solid ratio of at most 3:1, and it may be heated.
