Leaching of rare earth elements from bentonite clay

Van der Watt, J.G.; Waanders, F.B. (The Southern African Institute of Mining and Metallurgy, 2012)

Due to increasing concerns of global rare earth element shortfalls in the near future, possible alternative sources of rare earth elements have recently become of economic interest. One such alternative is decanting ...
Reactivity of Fe salts in the destabilization of acid mine drainage employing mixing and shaking techniques without pH adjustment

Ntwampe, I.O.; Waanders, F.B.; Bunt, J.R. (Elsevier, 2016)

Ferric chloride and Fe-sulphates are commonly Fe-salts used in water treatment, and the iron ionizes to form Fe3 + or Fe2 + when reduction occurs. A volume of 200 mL acid mine drainage (AMD) sample was poured into five 500 ...
Synthesized af-PFCl and GG-gP (AN)/TEOS hydrogel composite used in hybridized technique applied for AMD treatment

Fosso-Kankeu, E. (Elsevier, 2018)

In the present study af-PFCl, GL-g-P(AN) hydrogel and GL-g-P(AN)/TEOS hydrogel composite were synthesized. The hydrogels were characterized using the fourier transformed infra-red (FTIR) and the scanning electron microscope ...
