Fine Ore Surge Tunnel Conveyor Study Forbes, Minnesota

Project Description: United Taconite is a large pellet plant
operation at Forbes, Minnesota. Their product is taconite pellets, sold and shipped to steel plants around the world.
They currently have five lines of fine ore running into the concentrator building, where it is milled, separated and
screened into concentrate before being sent into the
pellet plant.

Cliffs Natural Resources requested Krech Ojard and Associates (KOA) to provide engineering services for a feasibility
study of installing new feeders and new conveyors in the reclaim tunnel underneath the Fine Ore Surge Pile at the
United Taconite Fairlane Plant in Forbes, Minnesota. This new equipment will be used to reclaim the current “dead” storage
located at the east end of the facility. 3d modeling of the facility was utilized during the review and design phases
of the project.
