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 کاملAnalysis of Acid Rock Drainage (ARD) with Micro Plasma Atomic Emission Spectroscopy (MP AES) – Comparison with ICP-MS
Analysis of dissolved metals in acid rock drainage (ARD) with an Agilent 4100 MP AES instrument that combines a nitrogen micro plasma with atomic emission detection (MP AES) was compared with an ICP-MS. Sample preparation consisted only of filtration, acidification (HNO3 1%) and addition of internal standard elements after appropriate dilution. In these complex matrices the systems gave identic...
متن کاملLong-term Performance of Passive Acid Mine Drainage Treatment Systems
State and federal reclamation programs, mining operators, and citizen-based watershed organizations have constructed hundreds of passive systems in the eastern U.S. over the past 20 years to provide reliable, low cost, low maintenance mine water treatment in remote locations. While performance has been reported for individual systems, there has not been a comprehensive evaluation of the perform...
متن کاملLong-term urethral catheter drainage.
SIR,-On behalf of my coauthors, I wish to thank Sir Eric Riches and Dr S L 0 Jackson for their comments (24 November, p 1367). In our enthusiasm to persuade others to adopt the domiciliary approach to long-term urethral catheter management we did not stray into an account of alternative measures, some of which are better suited to hospitalised patients. Sir Eric and Dr Jackson have correctly st...
متن کاملChemical stability of acid rock drainage treatment sludge and implications for sludge management.
To assess the chemical stability of sludges generated by neutralizing acid rock drainage (ARD) with alkaline reagents, synthetic ARD was treated with hydrated lime (batch and high-density sludge process), limestone, and two proprietary reagents (KB-1 and Bauxsol). The amorphous metal hydroxide sludge produced was leached using deionized water, U.S. EPA methods (toxicity characteristic leaching ...
