US Patent:

46505679, Mar 17, 1987

Filed:

Mar 4, 1985

Appl. No.:

6/707664

Inventors:

Phillip E. McGarry - Palmerton PA
David E. Herman - Jim Thorpe PA
Robert A. Treskot - Walnutport PA
David C. Fistner - Bethlehem PA

Assignee:

The Standard Oil Company - Cleveland OH

International Classification:

B03D 114

US Classification:

209166

Abstract:

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.

International Classification:

C10L 132

US Classification:

44 51

Abstract:

Process for the beneficiation and recovery of low rank coals comprising subjecting pulverized low rank coal to surface treatment by admixing said coal with an aqueous mixture comprised of a polymerizable monomer, a polymerization catalyst and a coal derived oil; and the beneficiated low ash, low sulfur containing product resulting therefrom.
