File:Specularite (high-grade iron ore) (Soudan Iron,

The rock shown above is specularite, which is a high-grade iron ore and the mining target at the Soudan Mine. Specularite is a finely-crystalline to coarsely-crystalline metamorphic rock dominated by silvery-gray specular hematite (Fe2O3 - iron oxide). "Specular" means "mirror" - it refers to the shiny, intensely lustrous appearance of each specular hematite crystal flake. SpeculariteRock Science: Minnesota's Banded Iron Ore | Rock & Gem,,09.01.2020· The two types of Minnesota’s banded iron ore are specularite and taconite. Specularite is a high-grade ore with well-defined, alternating layers of reddish chert and dark, glittery hematite; taconite has dark-gray bands and is much lower in grade. They share a common origin and are among the oldest ores ever mined.File:Specularite (high-grade iron ore) (Soudan Iron,,The Soudan Mine targeted high-grade iron ore (specularite) for many decades and closed in the early 1960s. The site is now accessible to the public and underground tours are offered. Observed iron-rich lithologies in the Soudan Iron-Formation include specularite, jaspilite BIF, and magnetite BIF.

Specularitic Iron Ores and Shear Zones in the Quadriltero,

In the eastern high-strain domain of the Quadriltero Ferrfero, Brazil, hard and soft high-grade hematite ore may occur as schistose bodies in shear zones mainly related to the Cambotas-Fundo thrust system. These orebodies are almost entirely constituted of oriented specularite platelets that develop both as a product of crystal-plastic deformation of hematite and solutionHematite Specularite – My Lost Gems,11.04.2020· It is mined as the main ore of iron. Specularite is a variety of Hematite characterized by aggregates of silvery, metallic, specular (‘mirror-like’) hematite flakes or tabular, anhedral crystals. Specularite, from MoroccoStrengthening granulation behavior of specularite,,22.09.2018· Six kinds of imported iron ores including a Brazilian specularite concentrate (SC), two kinds of limonite iron ores, a semi-limonite iron ore and two kinds of hematite iron ores were used in this study. Ore-A and Ore-B were limonite ores from Australian. Ore-C was a semi-limonite ore from Australian. Ore-D and Ore-E were hematite ores from Brazil. Besides, Ore
