Abstract

154,702. Jackson, W. J. Mellersh-. (Metals Recovery Co.). Sept. 2, 1919. Surface-tension separating processes. - A method of concentrating bituminous coal or refuse or waste consists in subjecting the coal to a grinding or crushing operation of such a kind as to yield a product having sharp angular edges and lustrous surfaces, and subjecting such product to separation by froth flotation. The flotation may be effected with the aid of suitable oils or oil mixtures, in the presence, if necessary, of acid or alkaline liquors, and such liquor may be separated from the tailings and used again.
