Prediction of the nature of effluents released from mine sites and their environmental impacts is a challenging and dynamic problem as AMD is affected, both by the textural and compositional features of sulphide ores and their weathered spoils and by water-rock interactions in receiving waters. This thesis examines AMD processes in the headwater region of the Tintillo River (a high level tributary of the Odiel River) that receives effluents draining the spoil heaps of the Corta Atalaya (CA) mine, Iberian Pyrite Belt (IPB), South-West Spain. The district and CA itself represent some of the largest massive sulphide mines in the world. The aim of the work presented here is to assess AMD generation and impacts around the CA mine focusing on, (a) AMD generation processes in the mine and its spoil heaps and (b) the impacts of site AMD on river water chemistry and river morphology....
