      Ever since their discovery in , the iron-formations and associated ore deposits of the Cuyuna iron range in east­ central Minnesota (Fig. 1) were known to be manganiferous. Ferromanganese ores were mined from several places on the North range from to , and stockpiled ore is still being shipped for making specialty steel. Cuyuna North Range, Crow Wing Co., Minnesota, USA: District consists of a semicircular area 5 miles in diameter north-northwest of Ironton, Minnesota. The ores are typical banded iron formation that have been metamorphosed and later concentrated into.

      The Mesabi Iron Range is an elongate trend containing large deposits of iron ore, and the largest of four major iron ranges in the region collectively known as the Iron Range of ered in , it is the chief iron ore mining district in the United States. The district is located in northeast Minnesota, largely in Itasca and Saint Louis counties.
