    The initial iron oxy hydroxide mineralogy and associated phases such as carbonates, quartz, apatite and phyllosilicates were transformed leading to an upgrading of these BIFs into the worlds largest source of iron ore. In low-grade BIFs, a large part of the iron is related to micro- and nano- metric iron-bearing inclusions within micrometric ...

    Sep 06, 2013 The deposit was discovered in 1844 and ore was first mined there in 1848, as per the State of Michigans website. Among the four types of iron ore deposits found in this area are magnetite and hematite ore. In Minnesota, magnetite iron ore is mined mainly in the Mesabi iron range, one of the four ranges that make up the Iron Range of Minnesota.

    Effect Of 25 Goethite On The Hydrophobicity And Oleate

    Jan 02, 2012 Flotation tests conducted on the two Iron Duke samples using oleate showed that the presence of goethite adversely affected the flotation response of the hematite but contact angle measurements showed a higher hydrophobicity for the sample containing 25 goethite. Correcting the oleate addition for the changes in surface area still showed that the goethite reduced the flotability of the hematite.

    Goethite Mineral Physical Optical Properties Uses

    Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore deposit.
