Dakota Aggregates LLC, which is in its second season operating a brand new processing plant, mines on 1,722 acres within the University of Minnesota Outreach, Research and Education (UMore) Park. The mine is located in Rosemount, Minn., within reach of the Twin Cities metro area. The operation was designed with innovation in mind, particularly where material handling is concerned. The site spans three miles from north to south, and a mile and a half from east to west. Overland conveyor systems were chosen to efficiently transfer material from the face to the processing facility while eliminating the use of loaders and haul trucks. The conveyors are reportedly quiet while minimizing energy use and lowering operating costs per ton.
