الإجراء التجريبي

In 1970, Richmond et al ('641 supra) reacted phosphate rock with phosphoric acid and then with sulfuric acid. The resulting acidulate was subsequently neutralized with anhydrous ammonia to produce a 7-21-0 (N--P2O5 --K2O) grade slurrey fertilizer. In later investigations Pottgiesser et al ('162 supra) produced a 13.5-6-0 (N--P2O5K2O) grade slurry by reacting nitric acid with phosphate rock and subsequently feeding the resulting slurry into a body of preneutralized solution maintained at pH 7-10 by addition thereto of aqua ammonia.
