Molybdenum is both an essential nutrient and a potential element of concern. The response to elevated molybdenum concentrations depends on a number of factors including the type of species, the mode of exposure, and the presence of other potentially mitigating factors. One important consideration for reclamation has been that much of the previous research on the environmental effects of molybdenum was carried out on substrates with a very different geochemistry than that found at BC mine sites.
The papers presented at the workshop have been divided into those dealing with terrestrial issues and those dealing with aquatic issues. Major themes to be discussed include procedures for risk assessment in reclamation planning, potential approaches to terrestrial reclamation and mitigation, and the importance of the water use in determining receiving environment objectives. Six of the papers are directly or indirectly related to the extensive work carried out by Noranda Inc. at the Brenda mine. Three others concern aspects of the work being carried out at the Endako Mine, with single papers describing reclamation-related work at Highland Valley Copper and Island Copper.
