Acid leaching of heavy metals from bentonite clay, used in the cleaning of acid mine drainage

Enslin, F.; Van der Mey, L.; Waanders, F. (SAIMM, 2010)

Heavy metals and sulphates in acid mine drainage (AMD) can be adsorbed onto bentonite clay, leaving clean water and a heavy metal loaded clay precipitate as products. Due to the toxicity of heavy metals, the clay could ...

Coagulation/flocculation potential of polyaluminium chloride and bentonite clay tested in the removal of methyl red and crystal violet

Fosso-Kankeu, E.; Webster, A.; Ntwampe, I.O.; Waanders, F.B. (Springer, 2017)

This study investigated the influence of the physico-chemical properties of methyl red (MR) and crystal violet (CV) on their removal by bentonite clay and polyaluminium chloride (PACl). Different dosages of bentonite clay, ...

Unique challenges of clay binders in a pelletised chromite pre-reduction process.

Kleynhans, E.L.J.; Beukes, J.P.; Van Zyl, P.G.; Kestens, P.H.I.; Langa, J.M. (Elsevier, 2012)

Ferrochrome producers strive towards lower overall energy consumption due to increases in costs, efficiency and environmental pressures. In South Africa, in particular, higher electricity prices have placed pressure on ...

Unique challenges of clay binders in a pelletised chromite pre–reduction process : a case study

Kleynhans, Ernst Lodewyk Johannes (North-West University, 2011)

As a result of increasing cost, efficiency and environmental pressures ferrochrome producers strive towards lower overall energy consumption. Increases in local electricity prices have placed particular pressure on South ...
