2021-7-12 Specializing in mine rehabilitation of coal, gold and chrome mines, Marmac Mining is an ideal mining contractor in multiple regions across South Africa. Afri Sand & Stone aims to become a signature brand in the supply of high quality, cost effective sand & stone building materials.
Dakota Mining and Quarry Equipment is a South African based company providing the local mining and quarry industry with the latest and most reliable equipment to date. Dakota Mining and Quarry Equipment have been appointed sole agent for Africa for equipment supplied and manufactured by Fisher Industries of
Sand, an important input to the construction industry, is extensively mined from the environment leading to depletion of the resource as well as damage to riparian habitat and the alteration of river beds and banks. Sand mining in South Africa is controlled by a complex regulatory system that can be distilled into three main themes: mineral regulation; environmental regulation; and land use planning regulation.
2020-10-5 the alteration of river beds and banks. Sand mining in South Africa is controlled by a complex regulatory system that can be distilled into three main themes: mineral regulation; environmental regulation; and land use planning regulation. In this thesis, it is hypothesised that sand mining is subject to all three regulatory themes equally.

2019-7-4 This analysis sought to explore regulatory and policy implications of sand mining operations along a sample of sites of Njelele River in South Africa. Data were gathered through observation, household questionnaire survey and a series of Participatory Rural Appraisal (PRA) exercises conducted with selected community members and sand miners.
2017-10-24 In this study, the impacts of sand mining on sediment textural characteristics and heavy metal concentrations of twelve metals (Al, As, Cr, Cu, Fe, Pb, Mn, Ni, P, Ti, V and Zn) and three nutrients, Ca, Mg and P and their impacts for instream and riparian biota are presented for two important river systems, the Mvoti and the Mdloti Rivers of KwaZulu-Natal, South Africa.

2018-12-7 This has led to extensive extraction of sand from rivers and other parts of the land; as a result, sand mining has considerable negative impacts on the fluvial environment and surrounding villagers. This study was carried out in order to identify and assess the environmental impacts of sand mining along Nzhelele River in Nzhelele villages.

2014-6-13 Two different methods—Matrix method and Rapid Impact Assessment Matrix method are used here to assess the environmental impact of sand mining in the longest river of Kerala—the Periyar river. The study reveals that the activity is a major threat to the very existence of the Periyar river in particular and the small rivers of tropics in general.
