1. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction
Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE

2. Geochemical and Mineralogical Characterization of Waste Rocks for Preliminary Mine Drainage Quality Prediction
Abstract : Acid or neutral rock drainage (ARD or NRD) with its attendant elevated concentrations of harmful elements presents one of the main challenges related to the management of waste rocks. Low-quality drainage is a particular issue with respect to mineral deposits containing sulfide minerals, of which pyrite and pyrrhotite are especially prone to produce acidic drainage when exposed to oxygen and water.
