Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
(EARET, 2018)
The effect of porosity of coal tailings on the
mobilization and speciation of heavy metals is important for the
implementation of management strategies. In this study, column
leaching experiments were carried out to ...
Reduction of salinity of water using acrylamide-based polyampholyte
(EARET, 2018)
Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ...
Prediction of dissolution of copper from a chalcopyrite carbonatite ore of South Africa
(EARET, 2018)
Chalcopyrite accounts for 70% of all copper bearing
minerals and therefore has been studied closely to understand the
dissolution kinetics in hope of overcoming the passivation film and
increasing the extraction rates ...
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
(EARET, 2018)
Coal mining operations produce large amounts of
tailings which contains heavy metals. Heavy metals such as
cadmium (Cd) can cause environmental problems. The adsorption
capacities of biochars produced from spent coffee ...
Photocatalytic degradation of naphthalene using tin dioxide nanomaterial under visible light
(EARET, 2018)
Coal processing in the refinery industry often lead to
the formation of coal tar containing polycyclic aromatic
hydrocarbons which are likely to affect human and animal health
when released in surface and ground waters. ...
Biological reduction of COD and sulphate by SRB in anaerobic moving bed biofilm reactor under high metal loading conditions
(EARET, 2018)
The performance of an anaerobic moving bed
biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for
the treatment of raw acid mine drainage (AMD) was investigated
for the reduction of sulphate and chemical oxygen ...
Recovery of iron nanoparticles from mine wastewater using plant extracts of Eucalyptus Globulus, Callistemon Viminalis and Persea Americana
(MDPI, 2020)
Mine wastewater (MW) is often rich in heavy metals that can have measurable effects on humans. The storage and treatment of MW remains a challenge for most mining companies. Iron (Fe) in MW was removed by using extracts ...
Investigation of effective chemical flocculation conditions for the treatment of reverse osmosis reject water from coal power plant: a case study
(Desalination Publications, 2020)
Power generation processes generate wastewater that is rich in scale-forming agents and which,
therefore, requires suitable pre-treatment prior to further treatment with an RO system. In this
study, Rheofloc5023 was used ...
Biosorption of Fe (II) from aqueous solution by brewing waste: equilibrium and kinetic studies
(Japan Society on Water Environment, 2019)
The physicochemical analysis of surface water of Mooi and Vaal rivers network indicated that the concentration of iron was far above the required limit by the South Africa water regulation. In this study, brewing waste was ...
Metagenomic profiling dataset of bacterial communities of a drinking water supply system (DWSS) in the arid Namaqualand region, South Africa: source (lower Orange River) to point-of-use (O'Kiep)
(Elsevier, 2019)
The metagenomic data presented herein contains the bacterial community profile of a drinking water supply system (DWSS) supplying O'Kiep, Namaqualand, South Africa. Representative samples from the source (Orange River) to ...
