Abstract
Improvements introduced in the object of the Main Patent nº 331,442 granted on March 16, 1967, for: "Procedure for the production of high purity aluminum nitrate solutions" characterized by comprising heating at a temperature of 140 to 220ºC and under pressure an aluminous mineral in which the weight ratio of aluminum, expressed as Al2O3 to iron, expressed as Fe2O3, is from 12: 1 to 20: 1, preferably from 14: 1 to 20: 1, and aqueous nitric acid with a concentration of 15 to 35% by weight, preferably 20 to 30% by weight, in a lesser amount than theoretically necessary to convert all the aluminum in the mineral to aluminum nitrate, preferably 60 to 85% of the amount theoretically necessary, and separate the iron-containing precipitate thus produced from the aluminum nitrate solution, heating in the first stage in the time necessary for the aluminum nitrate solution obtained in In the second stage, the weight ratio of aluminum, expressed as Al2O3 to iron, expressed as Fe2O3, is at least 2000: 1.
