The primary aim of this study was to synthesize cryptocrystalline magnesite–bentonite clay
composite by mechanochemical activation and evaluate its usability as low cost adsorbent
for neutralization and attenuation of inorganic contaminants in acidic and metalliferous mine
drainage. The composite was synthesized at 1: 1 weight to weight ratio. The capacity of the
composite to neutralize acidity and remove toxic chemical species from synthetic and field
AMD was evaluated at optimized conditions. Interaction of the composite with AMD led to an …

In the present study, nanocomposite of cryptocrystalline magnesite-bentonite clay was used
as a novel technology for removal of phosphates from municipal effluents. Vibratory ball
miller was used for fabrication of the composite. Removal of phosphate from an aqueous
solution was achieved using batch experimental procedures. The parameters optimized
include time, dosage, concentration and pH. An optimization experiment revealed that 30
mins of shaking time, 1 g of composite, 100 mg L− 1 of phosphate, 1: 100 S/L ratios, 250 …
