| abstract | 1,161,290. Treated leonardite ore. CONCHO PETROLEUM CO. 23 Jan., 1968 [20 Oct., 1967], No. 3439/68. Heading C1B. Leonardite is ground to 80-200 mesh in the presence of water to form a slurry containing not more than 65% of water, the slurry is freed from heavy foreign matter by flotation or sedimentation and is admixed with an excess of aqueous phosphoric acid for a sufficient time to convert the ore substantially completely to humic acids in the presence of such an amount of water that a content of 65% is not exceeded, the acid-treated slurry is ammoniated to pH 7-10 in the presence of recycled off-size product granules and added water to give a water content of 25-40%, the resulting granules are dried to a water content of 5-10% at a temperature of 170-200 F. in a concurrent stream of hot air, and are finally sized; 1 part of ammonia to up to 10 parts of total acid may be employed. Additional fertilizer (e.g. K 2 SO 4 , (NH 4 ) 2 PO 4 , NB 4 NO 3 , or urea) may be incorporated during granulation or blended with the dried and sized granules. |
