Usefulness of selected mineral wastes for reclamation of copper industry dumping site
Zofia Spiak , Krzysztof Gediga
AbstractIn the years 2007-2008, a potential utility of mineral wastes for reclamation of post-flotation sediment dumping site was tested. In the tests, use was made of barren rock, sand from a mine, overlay from a quarry, as well as phosphogypsum. They were used in the amount of 10% of sediment gravimetric capacity for pot experiments. Investigation proved that phosphogypsum and quarry overlay did improve those substrate properties which determine plant growth and development (pH and nutrient content). Additionally, phosphogypsum decreased the amount of substrate-soluble copper and zinc and, therefore, reduced their uptake by plants. According to the examination results, barren rock and mine sand considerably limited iron and manganese conversion into the forms easily assimilated by plants.
