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 ... -
Dispersion of inorganic contaminants in surface water in the vicinity of Potchefstroom
Manyatshe, A.; Fosso-Kankeu, E.; Van der Berg, D.; Lemmer, N.; Waanders, F. (Elsevier, 2017)Potchefstroom and the neighbouring cities rely mostly on the Mooi River and Vaal River for their water needs. These rivers flow through the gold mining areas and farms, and are therefore likely to be contaminated with ... -
Effect of temperature on the performance of Rheofloc: conductivity removal from RO-reject
Van der Linde, J.C.; Fosso-Kankeu, Elvis; Waanders, F.; Tamane, T.; Gericke, G. (EARET, 2018)South Africa is an arid country with an annual average rainfall less than half of the world’s average rainfall. The industrial sector uses 11% of this limited amount of water. Eskom is one of these users. Within the ... -
Equilibrium, kinetic, and thermodynamic studies of lead ion adsorption from mine wastewater onto MoS2-clinoptilolite composite
Pandey, S.; Fosso-Kankeu, E.; Waanders, F.; Spiro, M.J.; Kumar, N. (Elsevier, 2020)This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was ... -
Hazardous particles from coal fires from Santa Catarina, South Brazil
De Medeiros, Diego; Waanders, F.; Oliveira, M.; Sa, F.; Taffarel, S. (International Pittsburgh Coal Conference, 2016) -
Metal ions adsorption affinity of clayey materials from the North West Province of South Africa
Fosso-Kankeu, E.; Waanders, F. (CUMTP, 2014)Local clays that are abundant in the periphery of Potchefstroom in South Africa were characterized and investigated as potential sorbents for the removal of metal ions from effluents. The clay samples mostly contained ... -
Multifaceted nanominerals and ultrafine particles in phosphogypsum: a by-product of coal cleaning rejects
De Leão, Felipe B.; Waanders, F.; Taffarel, S.; Sampaio, C.; Lima, B. (International Pittsburgh Coal Conference, 2016) -
Preparation and characterization of gum karaya hydrogel nanocomposite flocculant for metal ions removal from mine effluents
Fosso-Kankeu, E.; Waanders, F.; Mittal, H.; Ntwampe, I.O.; Ray, S.S. (Springer, 2016)This research paper reports the removal of heavy metal ions from mine effluents using the gum karaya (GK)-grafted poly(acrylamide-co-acrylic acid) incorporated iron oxide magnetic nanoparticles (Fe3O4 MNPs) hydrogel ... -
Pretreatment of coal power plant ro retentate using AR Floc 100
Fosso-Kankeu, E.; Van Schalkwyk, L.; Waanders, F.; Gericke, G. (EARET, 2018)The water purification process at Eskom includes a reverse osmosis (RO) treatment plant. There are several limitations to this process depending on the water characteristics. The most common problems limiting the success ... -
Seasonal variation of hydrochemical characteristics of open-pit groundwater near a closed metalliferous mine in O’Kiep, Namaqualand Region, South Africa
Erdogan, I.G.; Fosso-Kankeu, E.; Waanders, F.; Ntwampe, S.K.O.; Hoth, N. (Springer, 2020)In this study, the hydrochemical characteristic changes of open-pit groundwater (OPGW) near a closed metalliferous mine proposed for drinking and irrigation usage were investigated. Water samples from an OPGW in O’Kiep ... -
Soil quality in the basin of mine effluents and the potential of alleviation of metal dispersion
Fosso-Kankeu, E.; Kaitano, R.; Waanders, F.; Mulaba-Bafubiandi, A.F. (CUMTP, 2014)The soils along the basin ofmine effluent were investigated for their role in the mitigation of the pollution of river water in the residential areas around Potchefstroom in South Africa.The results showed that the soils ... -
Time of flight secondary ion mass spectrometry and high-resolution transmission electron microscopy/energy dispersive spectroscopy: a study of the distribution of hazardous elements in coal ashes
De Medeiros, Diego S.; Waanders, F.; Oliveira, M.; Lima, B.; Botelho, L. (International Pittsburgh Coal Conference, 2017)
