| titleOfInvention | Recovery method of sodium contained in alkaline industrial waste |
| abstract | (57) Abstract: The present invention relates to a method for recovering alkaline industrial waste, and more specifically, sodium contained in "red mud" and sodium waste liquid from aluminum hydroxide production by the Bayer method, using an ion exchange resin. Things. It is an alkaline waste (1), generally "red mud" and a cationic resin (2) of the RH + type, to fix sodium selectively and quantitatively on the resin (5), preferably Contacting the carboxylic resin in the form of an aqueous suspension and then quantitatively extracting it in the form of NaOH (8) by transfer with a suspension of lime (6), preferably lime milk. Subsequently, the calcium-immobilized resin (9) is regenerated by the hydrochloric acid diluting solution (10) to elute calcium in the CaCl 2 state (12) and reuse it in the first step (2). |
