Abstract
As part of the Bureau of Mines research program on recovering alumina from domestic resources, methods for extracting iron from aluminum sulfate solutions (obtained by leaching kaolinitic clay with dilute sulfuric acid) were investigated. In countercurrent extraction experiments at a 1-gal/hr flow rate of aluminum sulfate leach liquor, the iron concentration was decreased from 1.4 G/l to 0.01 Gl/l after four stages of using a primary amine extractant. The iron-loaded amine solution was regenerated in five stages using 3n sulfuric acid or in four stages using 6n sulfuric acid. The aluminum sulfate solution obtained was suitable for the preparation of alumina meeting cell-grade standards of less than 0.01 pct iron.
