An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith, such as ash and sulfur. In this arrangement, an improved open flow, spiral nozzle is positioned above a flotation tank having a bath therein, and sprays an input slurry through an aeration zone into the surface of the water. The spraying operation creates a froth on the water surface in which a substantial quantity of particulate matter floats, while other components of the slurry sink into the water bath. A skimming arrangement skims the froth from the water surface as a cleaned or beneficiated product.

This invention relates to an improved hydrogenation process wherein aromatic amines are hydrogenated to their ring hydrogenated counterparts using an improved rhodium catalyst and to the catalyst. The aromatic amines are represented by the formulas: ##STR1## wherein R is hydrogen or C. sub. 1-6 aliphatic, R. sub. 1 and R. sub. 2 are hydrogen or C. sub. 1-6 aliphatic, A is C. sub. 1-4 alkylene, NH, or ##STR2## n is 0-2, x is 1-3 and y is 1 to 2 except the sum of the y groups in Formula I excluding A may be 1. The rhodium catalyst is supported on titania bonded to silica or zirconia or bonded with silica, zirconia or titania from a sol or zirconia bonded with silica or alumina. The resulting catalyst has greater activity and attrition resistance. Zirconia bonded with silica or alumina also results in a catalyst with increased attrition resistance.
