Abstract
Procedure to remove zinc from industrial sodium aluminate liqueurs, originating from the attack of cinuxiferous bauxites, which consists of transforming it into sodium cincate soluble in insoluble zinc sulfide by adding sodium sulfide in the aluminate liquor after dilution, characterized in that introduces into the liquor, before separating the red sides, a quantity of zinc sufficient so that the content of zinc sulfide at the time of precipitation is at least 0.180 g of ZnS per liter of aluminate solution and that an amount of sodium sulfide corresponding to 0.125 to 0.2 g of S- per liter of purifying aluminate solution is used for precipitation.
