The design of the Stillwater Mine's Blitz Sand Backfill Plant involved optimizing the plant location between available delivery envelope, geologic structures and planned access in addition to the capacity to meet both current and expected backfill demand capacities. Lessons learned from previous sand backfill plants and other construction projects were leveraged to develop a plant that meets the needs of both operators and maintenance personnel. An overview of the completed project along with lessons learned through the design, excavation, construction, and commissioning of the project will be covered.
