The recovery of lithium as lithium aluminate from Dead Sea brine and End brine (remaining after potash production) was investigated. In order to obtain high yields (90%) the End brine and the Dead Sea brine have to be diluted. The optimum pH range is 6. 8-7. 0 for End brine and 6. 6-7. 2 for Dead Sea brine. Ca(OH)//2 can be used instead of ammonia in order to raise the pH. The optimum reaction time is about 3 h. The optimum amount of AlCl//3 multiplied by (times) 6H//2O added is 30-40 g liter** minus **1 of brine. The best yields are obtained at room temperature and decrease with increasing temperature.
