Assessment of two kinetic tests to predict the acid mine drainage in waste rock samples of a uranium mine
Acid mine drainage is the result of the oxidation process of sulfide bearing rocks. This process occurs when the sulfide material is exposed to atmospheric conditions. Under these conditions, successive oxidation reactions yield sulfuric acid generating acidic waters. This problem becomes more serious when the surrounding rocks are not able to neutralize the acid. The low pH condition of the dr...
متن کاملAdvances 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...

Sorption phenomena are known to play significant roles in metal mobility in mine drainage waters. The present study focuses on sorption phenomena controlling Ni concentrations in contaminated neutral drainage issue...
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 کاملTaxonomic and chemical assessment of exceptionally abundant rock mine biofilm
BACKGROUND An exceptionally thick biofilm covers walls of ancient gold and arsenic Złoty Stok mine (Poland) in the apparent absence of organic sources of energy. METHODS AND RESULTS We have characterized this microbial community using culture-dependent and independent methods. We sequenced amplicons of the 16S rRNA gene obtained using generic primers and additional primers targeted at Archaea...
