Faced with the recent copper emission data from Løkken, The Norwegian Directorate of Mining has started a search for other low-cost solutions which could be employed if the situation continues to deteriorate. One interesting alternative lies in mixing the mine water with naturally occurring minerals in order to remove copper through the actions of partial neutralisation and adsorption. The aim is to remove copper from solution without simultaneously removing substantial amounts of iron, thus avoiding the problems associated with handling and depositing huge volumes of
