  • Synthesis of zeolite A using the waste of iron mine

    Synthesis of zeolite A using the waste of iron mine

    However, the aluminum content in iron mining tailings should be lower or zero, and it is clear that iron content in these residues is higher. As a result, an aluminum source must be added for zeolite synthesis. The goal of this work was to study the synthesis of zeolites A and its use in the treatment of effluent from the electroplating
