Column leaching of fine coal tailings: impact on environment and thickener operation
(EARET, 2018)The coal mining sector is synonymous with generating large quantities of waste. A comprehensive fraction of the waste is classified as fines (-500 µm) and ultrafine (-100 µm) particles, which accounts eleven per cent ... -
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 ... -
An electrochemical investigation of the dissolution of platinum employing AICI3/HNO3
(North-West University, 2014)Industrial activities of mankind are feared to damage the environment irretrievably. Especially the release of huge amounts of harmful gases causes concern. In this regard the environmental pollution caused by the one ... -
Environmental impact of leach water from selected mine tailings materials in South Africa
(North-West University (South Africa), 2019)Background and objective: Mine tailings materials pose severe impacts to the environment (soils, water and ecosystem). A variety of processes such as erosion or sedimentation and leaching disperse trace elements to the ... -
In vitro determination of the endocrine disrupting capacity of microplastics
(North-West University (South Africa), 2022)Since the development of plastic in the early 20th century, it has become essential in day-to-day living. The demand for plastic has grown exponentially to a point where there are over 300 million tonnes of plastic produced ... -
'n Studie om die potensiaal waaroor Chrysopogon zizanioides beskik om gekontamineerde oppervlakwater te remedieer, te bepaal
(North-West University (South Africa), 2022)This study was motivated since metals are contributing to a decline in the quality of surface water. During this study, the phytoremediation potential of Chrysopogon zizanioides has been evaluated for its ability to ...
