  • THE IRON RANGES OF MINNESOTA Mining History Association

    "The Cuyuna iron range in eastcentral Minnesota is unique in the Lake Superior region because of its large manganiferous ironore resources. It consists of three areasthe Emily District, the North range, and the South range. Although much smaller than the Mesabi iron range to the north, the Cuyuna was a major producer of iron ore for 80 years.

    The process is highly flexible with regards to iron ore reducing gas sources. Plants can operate at a wide spectrum of hydrogen to carbonmonoxide ratios (0.5 to 3.5) (Eliot and Kopfle, undated) This DRI production process is highly energy efficient and further energy gains are realized if the hot DRI is immediately transferred to the EAF melt shop.

    Use for energy balances. Sankey diagrams are ideal for visually representing energy balances. This is because an energy balance represents the contribution and flow of various energy commodities (fuels, heat and electricity, i.e. energy carriers in a marketable form) into the different sectors of the economy (e.g. supply, transformation and consumption) in energy units.

    In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow). The human brain, particularly the hypothalamus, plays a central role in regulating energy homeostasis and generating the sense of hunger by integrating a number of
