Reclamation of tailings storage facilities with sustainable technologies is an evolving area of study that is significant in achieving post-mining end land use capabilities.  Mine tailings, characterized by nutrient deficiencies and potential heavy metal contamination, present challenges to ecosystem development. Surface accumulation of mine tailings and waste can alter soil biogeochemistry and impact crucial factors for vegetation growth. This research focuses on the practical approach of covering tailings with subsoil and topsoil while enriching the soil with amendments. A greenhouse trial was conducted to assess the effects of zeolite, leonardite, and fortified compost on the growth of bluebunch wheatgrass under controlled environmental conditions. Additionally, a field soil amendment trial was performed to examine the impacts of amendments on plant growth, soil fertility, and heavy metal uptake in plants across different soil cover depths. By conducting these trials, this research aims to provide valuable insights into the utilization of mining by-products (zeolite and leonardite) in combination with compost, as well as to identify an appropriate soil cover depth for sustainable tailings management.
