Abstract

186,143. Price, F. G., and Minerals Separation, Ltd. June 20, 1921. Flotation processes.-In the flotation process for the separation of different kinds of coal, the flotation of fusain and other undesirable constituents is prevented by the addition of a small proportion of a protective colloid, with or without the assistance of a frothing-agent such as cresol or paraffin, previous to the aeration and agitation of the pulp. The protective colloid may be tannin, tapioca, maize-flour, egg albumen or blood albumen, caseine neutral or alkaline, animal gluten, gelatine, glues, cutch, or agar-agar.
