The Cleveland Iron Mining Company was one of the pioneering producers in the Lake Superior Iron Mining District by 1890. In 1850, the Michigan legislature chartered the Cleveland Iron Mining Company with operations centered in Ishpeming, Michigan. Over the next 40 years, many iron mining companies formed, failed, or merged into the.

Apr 01, 2016 Iron ore in the Lake Superior basin fell into two broad types high-grade ores (often called “direct shipping ores” because such ores required minimal processing before shipping), and low-grade ores which required expensive beneficiation an expensive and technically challenging process involving crushing, screening, grinding, magnetic separation, filtering and finally drying (Manuel, 2013.

The only other known deposit of ore lay in the inhospitable forests near the southern shore of Lake Superior. Nonetheless, when William Burt and his surveying team discovered iron ore along the southern Lake Superior shore in 1844, it hardly caused a stir. In fact, none of the party even bothered to file a claim on any portion of the area.

Oct 05, 2016 The hematite deposits of the Lake Superior region are of sedimentary origin, but the rich ores have undergone natural concentration from the lean ores of the iron formation. These formations are widespread in eastern Canada and the United States but in only a very small part of the known areas (about 2 in the U.S.A.) have merchantable ores.

The majority of historical iron mining activities in Wisconsin involved the removal of high-grade (direct-shipping) ore, which was mined in several areas throughout the state. The major remaining deposits are taconite, a low-grade (typically 20-30 iron) ore that requires processing to increase the iron content and remove impurities.
