Modeling Irrigation with Gypsiferous Mine Water: A Case Study in BotswanaInternational journal of mine water - Tập 20 - Trang 65-72 - 2001
N.Z. Jovanovic, J.G. Annandale, A.S. Claassens, S.A. Lorentz, P.D. Tanner
The possible use of mine effluent for irrigation of agricultural crops was investigated for BCL Ltd. nickel mine (Selebi Phikwe, Botswana). The aims were to estimate the long-term water and salt balance under irrigation with gypsiferous mine water, as well as to make recommendations on cropping and management options. A simple but mechanistic edynamic soil water-salt balance generic crop growth m...... hiện toàn bộ
Development and Validation of a Spectrophotometric Method to Measure Sulfate Concentrations in Mine Water without InterferenceInternational journal of mine water - Tập 30 - Trang 169-174 - 2011
Arup Roy, Bidus Kanti Das, Jayanta Bhattacharya
Sulfate concentrations are determined in mine water by gravimetric, titrimetric, colorimetric, turbidometric, ion chromatographic, inductively coupled plasma absorption spectrophotometric, and other methods. Accurate sulfate measurement of mine water can be difficult due to interfering groups, cations, and anions, mainly arsenate (AsO4
3−) and phosphate (PO4

Holistic Design of Wetlands for Mine Water Treatment and Biodiversity: A Case StudyInternational journal of mine water - Tập 41 - Trang 292-299 - 2022
André Sobolewski, Noah Sobolewski
Passive treatment wetlands are conventionally designed with the primary objective of purifying contaminated mine water; any benefit of enhanced biodiversity is ancillary. We propose a new approach that incorporates enhanced biodiversity as an explicit objective. In this approach, treatment units are selected based on water flows and chemistry and the ecological requirements of key species are iden...... hiện toàn bộ
