Abstract
The surface waste materials or tailing discarded from mineral processing activities results in a unique environment which, potentially, can severely inhibit surface and subsurface stabilization. Mineral tailing materials contain residues from metal ore processing operations and are often excessive and/or deficient in chemical, physical, and biological properties necessary for stabilization through revegetation. As a result, there is a need for the development of treatment technologies to remediate active and abandoned mineral waste materials. To investigate the potential of organic residues as a physical agent to ameliorate the chemical, physical, and biological limitations of tailing materials for vegetative stabilization, the USBM has implemented a series of experiments at active and abandoned mineral mine tailing sites in northeastern Minnesota and southeastern Kansas. In each climatic zone, vegetative cover has improved depending on the type of organic residue used and rate of application. Total cover has progressively increased over 5 years at all experimental sites and has not reached steady state conditions. A potential new strategy for reclaiming difficult sites through the use of organic residues is proposed.
