  • Effect of 25% Goethite on the Hydrophobicity and Oleate

    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.

  • Effects of Si-bearing minerals on the conversion of

    In summary, the inhibitory effect of Si-bearing minerals on hematite to magnetite conversion in Bayer digestion can be explained by the fixation of DSP particles on the hematite surface: (1) reducing the direct adsorption of aqueous Fe (II) and influencing the interfacial electron transfer, and/or (2) blocking the soluble sites on hematite or

  • Effects of Pretreatments on the Zeta Potential

    The effects of pretreatments on the zeta potential characteristics of hematite were investigated on a number of hematite samples. The bulk of the test work was conducted on a sample of naturally occurring hematite from the Iron Prince deposit in the Middleback Range area of South Australia. The iep of the ROM ore was measured as 2.6, which was only slightly raised by ultrasonic cleaning.

    Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
