This is Magnetic Taconite , part of Minnesota's iron formation and in many ways similar to other iron-bearing materials found in the United States and throughout the world., Forty years of work in mining firms' laboratories and at the University of Minnesota developed methods for processing taconite's meager iron content into a competitive iron ore product. Thus, taconite processing plants represent new jobs for miners and new opportunities for those who supply or serve them., New taconite plants were welcomed to Minnesota when her voters November 3, 1964, endorsed the principle of fair tax treatment for huge investments a taconite plant entails. The mining companies, in turn, responded immediately and again demonstrated their faith in the State by starting construction of new facilities which will expand taconite job-producing investments to exceed a billion dollars , the largest new industrial investment in the State., One of Minnesota's new taconite plants will be located here at Mountain Iron, where Lon Merritt and his six iron men established the Mesabi’s first mine in 1890 and opened this area to development., The Merritts gave mining on the Mesabi its birth 75 years ago. Taconite now offers Mountain Iron and the Mesabi rebirth as major iron ore suppliers to an America still building!, July 25, 1965 . This historical marker was erected in 1965.
