Using passive treatment systems for mine closure -- a good approach or a risky alternative?

Mining Engineering, 2000, Vol. 52, No. 9, pp. 29-34
Eger, P.; Melchert, G.; Wagner, J.


ABSTRACT:
When iron ore was discovered in Minnesota in the 1880s, concern about the impact of mining on water quality was not a major issue. Fortunately, the majority of the rock associated with Minnesota’s iron ore does not contain acid-generating minerals. With the exception of erosion and sediment transport, there has been little impact on water resources. Consequently, when LTV Steel opened the Dunka Mine in 1962, little thought was given to the handling of waste rock from the operation.
