Abstract: A process for recovering thermal values and organic materials from solid carbonaceous fuels, i.e., bituminous coals and lignites, by contacting such fuels with waste foul condensates, known as black liquor, from pulping operations thereby to solubilize thermal value containing organic materials therefrom and simultaneously provide a use for the heretofore considered unusable black liquors, the disposal of which up to now has presented both an economical and ecological problem.

Abstract: A process for recovering oil from oil containing masses and formations by contacting such oil bearing masses with waste foul condensates, known as black liquor, from paper and pulping operations, thereby to free the oil present or bound up in such masses and simultaneously provide a use for the heretofore considered unusable black liquors, the disposal of which up to now have presented both an economical and ecological problem.

Abstract: 1. An explosive slurry composition comprising a substantially saturated solution of ammonium nitrate, and suspended solids in said solution to form said slurry, said solids being comprised of at least 50 parts by weight of ammonium nitrate, and not more than 50 parts by weight of finely divided metallic aluminum of character such as to increase the sensitivity of said composition to detonation, the total nitrate comprising at least 50% of the total composition, said composition including water comprising at least 3 percent by weight of the total composition. 2. An ammonium nitrate explosive composition consisting essentially of particulate ammonium nitrate in admixture with an aqueous solution saturated with respect to ammonium nitrate, and with up to 35 per cent by weight of an inorganic sensitizer which taken alone is a stable solid at a temperature of at least 100.degree.C., the amount of water being from 3 to 25 per cent by weight of the total composition. 3.
