Process for the production of low-iron zeolitic aluminosilicates

摘要

A process for the production of a low-iron zeolitic alkali metal aluminosilicate from iron-containing, optionally previously activated, mineral aluminosilicate raw materials comprising subjecting the iron-containing, optionally previously activated, mineral aluminosilicate raw material in a charge of suitable molar ratios of M2O : Al2O3 : SiO2 :
