The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite is white.Iron formationenrichment processes can occur through regional metamorphism associated withthe Hudsonian orogeny which increased grain sizes and often resulted in conversion of Fe oxide hematite to coarse magnetite. Metamorphism during the Hudsonian also contribute to the leaching d of silica and thereby enrichment of Fe taconite grades.

Learning Geology Iron Ore Mar 17, 2015 The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.Mar 17, 2015 The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.Furthermore, because of the small grain size of the iron oxide components of both hematite taconite and magnetic taconite, these ores are difficult to float by known direct flotation techniques. At this point, it should be noted that direct flotation is a process in which the iron oxide itself is

Magnetite can be removed from the siliceous waste materials by large electromagnets. Hematite requires a more sophisticated process for concentration.Aug 01, 2011 Some of the mineral deposits that are being processed today, and especially those expected to be processed in the future, have relatively low compositions of the valuable mineral. With these low-grade ores, it is necessary to be able to design processes that are sufficiently low-cost to permit exploitation. One approach to minimizing the capital and operating costs for these processes is
