The acid mine drainage (AMD) is characterized by its highly acidic nature and elevated concentrations of metal ions, thereby exerting significant impacts on both human health the environment. This study employed a dispersed alkaline substrate (DAS) consisting thermal activation magnesite pine shavings for treatment AMD. investigation focused determining optimal conditions magnesite, evaluating effectiveness DAS in regulating acidity removing ions from AMD, identifying critical factors influencing efficiency, conducting toxicity assessment effluent. Results indicated that calcination at 700 °C 60 min was determined to be condition magnesite. Under operating (flow rate: 0.4 mL/min, filling mass ratio: = 1:1), system achieved complete removal (100%) within 396 h while maintaining pH above 7.0. Moreover, it significantly minimized costs sludge generation. Toxicity experiments conducted using Chlorella proteolytica demonstrated reduction biotoxicity after with this system. These findings suggest based holds promise as an effective solution treating

Coal fly ash and acid mine drainage are significant environmental issues in South Africa, causing storage constraints impacting water quality. This study explores the use of coal preparing zeolite HBEA-supported Fe catalysts. The Na-BEA parent catalysts were synthesised hydrothermally using as a feedstock. was loaded upon H-BEA form liquid-phase ion exchange or wet impregnation, Fe-rich metal precursor. ion-exchanged Fe-BEA exhibited excellent activity, with highest selectivity achieved over 25 AHW after 0.5 h on stream. also found that when impregnation used to load onto support, other metals present AMD affected overall Mn, Ca, Mg, Na decreasing conversion selectivity, while Ni had promoting effect. demonstrates green solid high catalytic activity can be prepared two waste materials, drainage. To best our knowledge, we reporting for first time precursor catalyst preparation.
