An investigation into the problems associated with revegetating chrysotile tailings
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: L. van Rensburg --- , Republic of South Africa L. Pistoruis --- , Republic of South AfricaThe present investigation was initiated because of the limited success achieved in the past at attempts to revegetate chrysotile tailings with their associated inherent environmental risk factors. The current set of experiments and surveys, as with several previous studies, were... -
Rehabilitation of co-disposed kimberlite tailings: Quantifying physical and chemical properties from a rehabilitation perspective
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: L. van Rensburg --- , South Africa M.S. Maboeta --- , South AfricaMine rehabilitation is a complex process and the potential of revegetating kimberlite tailings (after being co-disposed) was evaluated in this study, with regard to physical and chemical properties. High water soluble Na concentrations (8.22 mmol -1) represent the most serious... -
Characterisation of alkaline tailings from a lead/zinc mine in South Africa and evaluation of their revegetation potential using five indigenous grass species
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: LouisW Titshall --- School of Agriculture, Earth and Environmental Sciences, South Africa JeffreyC Hughes --- School of Agriculture, Earth and Environmental Sciences, South Africa H Christopher Bester --- School of Agriculture, Earth and Environmental Sciences, South AfricaTailings from a lead/zinc (Pb/Zn) mine were characterised and their revegetation potential investigated under glasshouse conditions using five grass species with three rates of inorganic fertiliser. The tailings were alkaline with low nutrient concentrations but high total and extractable Zn... -
Establishing Cynodon dactylon on mining tailings and mining-impacted soil of a copper–cobalt mine in the Democratic Republic of the Congo
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: JE Granger --- SAEON, South Africa TG O'Connor --- SAEON, South AfricaMining for copper and cobalt generates extensive mounds of removed topsoil and subsoil, and tailings with toxic levels of copper and cobalt. The threat of soil erosion in a high rainfall regime can be countered with rapid establishment of a... -
The annual pattern of sap flow in two Eucalyptus species established in the vicinity of gold-mine tailings dams in central South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Peter Dye --- Ecological Engineering and Phytotechnology Programme, Restoration and Conservation Biology Research Group, School of Animal, Plant and Environmental Sciences, South Africa Alistair Clulow --- Agrometeorology, South Africa Eric Prinsloo --- CSIR, Built Environment, South Africa Vivek Naiken --- CSIR, Natural Resources and the Environment, c/o Agrometeorology, South Africa Isabel Weiersbye --- Ecological Engineering and Phytotechnology Programme, Restoration and Conservation Biology Research Group, School of Animal, Plant and Environmental Sciences, South AfricaSeveral hundred mine tailings dams occur in the Witwatersrand Basin Goldfields in central South Africa. Seepage of acid mine drainage (AMD) from these unlined structures is widespread, and a variety of contaminants is released into soil and groundwater. The ‘Mine... -
Spatio-seasonal dynamics of bacteria and metal composition of a platinum mine tailings dam, Rustenburg, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Molemi E Rauwane --- Agricultural Research Council–Biotechnology Platform, South Africa Laurette M Marais --- Department of Biotechnology, Faculty of Applied and Computer Sciences, Vanderbijlpark Campus, South Africa Oluwatosin G Oladipo --- Unit for Environmental Sciences and Management, South Africa Cornelius C Bezuidenhout --- Unit for Environmental Sciences and Management, South Africa Mark S Maboeta --- Unit for Environmental Sciences and Management, South AfricaSeasonal variations and proximity to polluted sites, among other factors, play a vital role in soil composition. The impact of spatio-seasonal changes on bacterial and heavy metal content on and around the platinum mine tailings dam, Rustenburg, South Africa, was...
