Automated Method for Assessment of Pit Lake Water Quality Risk using the Pit Quality Risk Assessment Protocol (PQRAP)

A pit lake water quality risk assessment tool was developed to characterise potential post-closure geochemical impacts from pit lakes. The risk is evaluated as a function of the pit water balance and geochemical criteria that are typically available at the pre-feasibility stage of mine development. The tool is applied in this paper using published data for the Rum Jungle minesite, south of Darwin in the Northern Territory of Australia to demonstrate the outputs that are generated.
