Abstract

PURPOSE: To recover higher purity In in a higher yield as compared to a conventional method by adding phosphoric acid to the titled bath, filtering a precipitate formed, and treating a soln. of the precipitate in hydrochloric acid with a cation exchange resin.
CONSTITUTION: Phosphoric acid is added to the titled bath to precipitate In, Ca, Mg, Pb and Ag alone as the phosphates. This precipitate is separated by filtration and dissolved in hydrochloric acid, whereby In alone forms chloroindate. The soln. is then treated with a cation exchange resin. Ca and Mg are adsorbed on the resin column, Ag and Pb stay on the column as a precipitate, and In is eluted immediately. This eluate is evaporated to dryness to easily recover high purity indium chloride in a high yield.
