Analysis of metal-laden water via portable X-ray fluorescence spectrometry
Pearson, Delaina; Koch, Jaco; Van Deventer, Piet; De Wet, Jandre; Weindorf, David C. (Elsevier, 2018)A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption ... -
Baseline status of microbial activity on gold tailings facilities in South Africa
Schimmer, C.; Van Deventer, P.W. (Elsevier, 2018)In many ways, South Africa’s landscape has been dominated by mining, given that, for so many years this sector has been the mainstay of the South African economy. As such the environmental impacts of these mining activities ... -
Effects of different soil ameliorants on Karee trees (Searsia Lancea) growing on mine tailings dump soil – Part I: Pot trials
Kotte, Karsten; Van Rensburg, Leon; Lange, Christian A.; Smit, Martin; Van Deventer, Peter W. (Taylor & Francis, 2012)Rehabilitation of mine tailings dams is often a challenge due to a lack of nutrients and a poor humus reservoir prevailing in tailings soils. This is especially true for establishing longer lived species such as trees. For ... -
The emergence and survival of Digitaria eriantha and Chloris gayana seedlings on mine tailings planted with coated and non-coated seed
Nel, Leana; Van Deventer, Piet; Kellner, Klaus; Truter, Wayne F. (CIAT, 2014) -
Humusica 2, article 16: Techno humus systems and recycling of waste
Zanella, Augusto; Schimmer, Claudia; Van Deventer, Piet; Ponge, Jean-François; Guercini, Stefano (Elsevier, 2018)Techno humus systems correspond to man-made topsoils under prominent man influence. They may be purposely conceived for supporting agricultural activities or dumping of waste products, sometimes abandoned to an unknown ... -
Monitoring the pollution effects from a gold tailing storage facility on adjacent land through Landscape Function Analysis
Daniell, Angelique; Van Deventer, Pieter W.; Malo, Dawid S. (Springer, 2019)Degraded landscapes adjacent to gold tailing storage facilities (TSFs) typically suffer from loss of ecosystem function as a result of seepage pollution. Restoration of these areas has become a primary concern in the fields ... -
An overview of pedogenesis in Technosols in South Africa
Daniell, Angelique; Van Deventer, Pieter W. (Taylor & Francis, 2018)Technosols are soils dominant in technical artifacts, formed from anthropogenic deposits or transported materials. While anthropogenic in origin, it is clear that pedogenic processes are active within Technosols, i.e. ... -
Pollution control of the Selati tailings storage facility by means of a decision support system: a case study
Daniell, Angelique; Van Deventer, Piet W. (CSEE, 2018)The Selati tailings storage facility (TSF) lies in the Limpopo Province in South Africa and originates from mining and the metallurgical processing of carbonatite and pyroxenite from the Phalaborwa Complex [1]. The Selati ... -
Proximal sensor analysis of mine tailings in South Africa: an exploratory study
Koch, Jaco; Van Deventer, Piet; Daniell, Angelique; Faull, Cindy; Chakraborty, Somsubhra (Elsevier, 2017)Proximal sensors have rapidly developed in-situ analysis of soil and sediment. Two systems in particular, portable X-ray fluorescence (PXRF) spectrometry and visible near infrared diffuse reflectance spectroscopy (VisNIR ...
