Abstract
PURPOSE: To recover high purity metal hydroxide or oxide in an easily separable state by adding NH3 or ammonia water to a metal salt-contg. soln.; separation- recovering the resulting precipitates of metal hydroxide or oxide; and adding an alkali agent to the separated soln. to liberate NH3.
CONSTITUTION: Soln. 1 contg. salt of metal such as Al, Mg, iron, Zn or Cd is charged into reaction vessel A and mixed with NH3 or ammonia water 11 to form precipitates of metal hydroxide or oxide. Reaction slurry 2 is introduced into separation vessel B and subjected to solid-liquid separation, and precipitated conc. sludge 4 is recovered. On the other hand, separated soln. 5 is introduced into separation vessel C and mixed with one or more kinds of alkali (earth) metal hydroxides or 6 to decompose NH4 salt in soln. 5 into NH3 and by-product salt. A soln. separated from vessel C or gypsum separation vessel D is then fed to stripping tower E, where NH3 in the soln. is stripped with stripping gas 9 introduced from the lower part. NH3 gas 10 is converted into ammonia water 11 in absorption tower F and returned to vessel A together with NH3 gas 8 from vessels C,D.
