Advances in Acid Rock Drainage (ard) Characterisation of Mine Wastes
Research was carried out to improve acid rock drainage (ARD) prediction methodologies, focussing on resolving uncertainties in acid base accounting (ABA) methods. Advancements, their application, and interpretation are reported. Consideration of both net acid production potential (NAPP) and net acid generation (NAG) test results provide a more reliable routine screening technique than either te...
متن کاملEvaluation of Rock Characteristics for Acid Water Drainage from Rock Muck
Surface/ground water pollution caused by the inflow of acid water enriched with heavy metals has become a serious environmental problem in the areas around mines [1,2]. This results from the sulfate discharge generated by the decomposition of pyrite contained in the altered rock in mining areas [3]. The same problem has arisen at engineering work excavation sites in recent years [4]. Therefore,...
متن کاملAcid Mine Drainage Prevention and Control Options
Acid mine drainage (AMD) is one of most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at operating and closed/decommissioned mine sites. AMD may adversely impact the surface water and groundwater quality and land use due to its typical low pH, high acidity and elevated concent...
متن کاملMulti-Output Adaptive Neuro-Fuzzy Inference System for Prediction of Dissolved Metal Levels in Acid Rock Drainage: a Case Study
Pyrite oxidation, Acid Rock Drainage (ARD) generation, and associated release and transport of toxic metals are a major environmental concern for the mining industry. Estimation of the metal loading in ARD is a major task in developing an appropriate remediation strategy. In this study, an expert system, the Multi-Output Adaptive Neuro-Fuzzy Inference System (MANFIS), was used for estimation of...
متن کاملCharacterization of Green Liquor Dregs, Potentially Useful for Prevention of the Formation of Acid Rock Drainage
Using alternative materials such as residual products from other industries to mitigate the negative effects of acid rock drainage would simultaneously solve two environmental problems. The main residual product still landfilled by sulphate paper mills is the alkaline material green liquor dregs (GLD). A physical, mineralogical and chemical characterization of four batches of GLD was carried ou...
