Air movement on and around tailings storage facilities on the Highveld of South Africa
(North-West University (South Africa), Potchefstroom Campus, 2017)Dust from gold tailings storage facilities (TSFs) is problematic in certain areas of the South African Highveld. Many of these localities around TSFs are densely populated, which often result in tailings dust being a ... -
Assessing the regional structural geological setting as fundamental component of the dolomite risk management process
(North-West University (South Africa), 2016)Dolomite stability investigations conducted within the confines of a pre-demarcated project area rarely take the regional structural geological setting into consideration. As such, the site selection process is very often ... -
Cenozoic deposits of South Africa
(North-West University (South Africa) , Potchefstroom Campus, 2016)The Cenozoic Era comprises the last 65 million years of Earth's history, which is divided into the Tertiary and Quaternary Periods. The deposits of the Cenozoic Era are reflected in many surface features covering South ... -
Correlations between vegetation, soil and geology in the semi-arid Bushmanland region of South Africa
(North-West University, 2018)Since the early 1900’s scientists have investigated the different factors that play a part in biodiversity and species richness with respect to vegetation composition. Plant species have different needs for nutrients, ... -
The development of a dolomite risk management strategy for the Tlokwe City Council
(North-West University, 2012)Development on dolomite poses a risk due to the possible formation of instability features such as sinkholes. Most of these features are however man-induced, and the risk associated with development on dolomitic areas can ... -
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 ... -
The environmental impact of small cap mineral exploration companies : a review of African activities and legislation
(North-West University (South Africa), Potchefstroom Campus, 2017)In recent decades, the extractive minerals industry’s impact on the environment has, for numerous reasons, been the object of intense scrutiny. Operating mines are under constant pressure to reduce the impact their ... -
The evaluation of coated and uncoated seed mixtures for the rehabilitation of gold and platinum mine tailings
(North-West University, 2018)The establishment of vegetation on platinum and gold Tailing storage facilities (TSFs) to stabilise the TSF surface against erosion (phytostabilisation) are met with many challenges; acid and alkaline pH levels of tailings, ... -
The evaluation of five coated and noncoated grass species for the rehabilitation of gold and platinum mine tailings in South Africa
(North-West University (South Africa), Potchefstroom Campus, 2016)Land use and, more recently, land rehabilitation has historically been, and remains, a key driver in the economic growth of South Africa. Environmental legislation as well as the involvement of all spheres of government ... -
Geochemical monitoring of soil pollution from the MWS-5 gold tailings facility on the Farm Stilfontein
(North-West University, 2015)The rehabilitation and restoration of degraded landscapes adjacent to gold tailings disposal facilities (TDFs) that have suffered loss of efficiency through anthropogenic forces has become a primary concern to environmental ... -
Geological related acid mine drainage of gold tailings and coal waste materials : a comparative study
(North-West University (South Africa). Potchefstroom Campus, 2018)The study is aligned with the mining industry’s transformation requirements using a range of combination of methods from quantitative to qualitative and action-based methods. Most sources of metal trace elements in the ... -
Growth potential of various plant species for vegetative rehabilitation of different mine tailings
(North-West University, 2015)Vegetation establishment is one of the major rehabilitation methods that are used to stabilize, cover, to minimize, mitigate or remove the contaminants from tailings storage facilities (TSF’s). Phytostabilization is a ... -
The implementation of a geo–environmental decision support system for development on dolomite
(North-West University, 2012)Due to the inherent hazardous characteristics associated with dolomite and development on dolomite, quantification of the stability attributes related to dolomite is essential. In large parts of South Africa, development ... -
The influence of neutralisation time lag on plant-available phosphorous in acid mine tailings
(North-West University (South Africa), 2019)The main goal of vegetation establishment on tailings storage facilities is to stabilise their slopes to improve the retention and infiltration of water, thereby reducing the effects of wind and water erosion. The ... -
Inoculation of carbon and nitrogen in growth mediums to promote seed germination in mine rehabilitation
(North-West University (South Africa), Potchefstroom Campus, 2015)The mining industry has been a vital component in the development of South Africa. Activities related to the mining industry have resulted in major impacts, both environmental and social. The rehabilitation of mining-disturbed ... -
Investigating soil algae and cyanoprokaryotes on gold tailings material in South Africa
(2014)Gold mine tailings material facilities are characterized by sparse vegetation and an abundance of dust. Mine tailings facilities are examples of extreme geotechnical and geochemical conditions which make it almost ... -
Migration and gamma ray assessment of uranium on a gold tailings disposal facility
(2014)This project aims to quantify natural gamma radiation in gold tailings disposal facilities (TDFs) relative to uranium concentration data in order to use natural gamma detection methods as alternative methods for uranium ... -
Nitrogen fixation of legumes in different growth mediums
(2015)South Africa has an array of mining commodities which all play an integral role in our everyday surroundings, income, and most importantly, in the economy of the country. These mining activities also produce vast amounts ... -
Seed viability and re-growth of grasses used for mine waste rehabilitation
(North-West University, 2014)Sustainable rehabilitation can be compromised by the inability of vegetation to survive in hostile mine wastes on a long-term basis. The adverse chemical and physical properties of mine wastes, together with extreme pH ... -
The selection process of analogue parameters and criteria for rehabilitation design at Sishen mine
(North-West University (South Africa), 2016)According to the South African Mineral Petroleum Resources Development Act, 2002, the holder of a mining right must, as far as is reasonably practicable, rehabilitate the environment affected by mining operations to its ...
