Abstract

LOS CONTAMINANTES DE METAL PESADO SE INMOVILIZAN A PARTIR DE REFINADOS QUE CONTIENEN ACIDOS DE FOSFORO. LOS REFINADOS SE NEUTRALIZAN A PARTIR DE AGLOMERADOS Y LOS AGLOMERADOS SE TRATAN ENTONCES PARA FORMAR UN MATERIAL SOLIDO SIMILAR A LA ROCA EN EL QUE LOS CONTAMINANTES DE METAL PESADO ESTAN PERMANENTEMENTE ENCAPSULADOS.
