Use of phytic acid for selective precipitation of undesirable metals (Al, Fe, Pb) contained in the leachates from hydrometallurgical processes

Autor: Nathalie Leclerc, Eric Meux, Julien Comel, Sébastien Diliberto

Publikováno v: Journal of Environmental Chemical Engineering. 9:105450

In hydrometallurgical processes, chemical precipitation is used either to recover dissolved valuable metals or to remove undesirable elements before electrolysis. Beside conventional reagents (Ca(OH)2, NaOH, Na2CO3…) many authors tried to replace t
