This project will evaluate multiple methods to control mercury emissions during the processing of taconite. Evaluations include injection of brominated sorbents into flue gas, upstream from wet scrubbers, as well as post-scrubber fixed carbon and baghouse methods. Activated carbon will also be added directly to the taconite pellet bed in the beginning of the taconite processing stream, as a means to oxidize mercury in process gases. The activities in this project will reduce mercury inputs into the Lake Superior basin.
