Formation of secondary mineral coatings and the persistence of reduced metal-bearing phases in soils developing on historic coal mine spoil
Acid mine drainage (AMD) from historic and abandoned coal mine spoil represents a
potential long-term source of contaminants to surface and groundwater. Determining the risk
associated within AMD generation and metal (loid) transport from coal mine spoil is
complicated by the heterogeneous natural of spoil heaps and mineralogical and hydro (bio)
geochemical factors that may limit or promote metal (loid) transport. The current work aims to
determine if primary, reduced phases such as pyrite continue to persist in abandoned and …
