Manoomin/psiη (wild rice) is a sacred plant for Native peoples throughout the Great Lakes region. Unfortunately, Manoomin has been declining due to multiple environmental stressors. Native people who have lived with manoomin / psiη for generations understand this intimately, but tribal views, concerns, and treaty rights have not been ...

Launched in January 2018, Kawe Gidaanaanaagadawendaamin Manoomin (First We Must Consider Manoomin/Psin) is a collaboration among tribes, intertribal treaty organizations, and University of Minnesota faculty, staff, and students, that prioritizes tribal views on the cultural significance and ecology of Manoomin / Psiη .
· Geology, Prospecting and Exploration for Iron Ore Deposits. Iron has been known since antiquity. Iron is ubiquitous in the lithosphere as either a major constituent or in trace amounts. In abundance it ranks fourth behind oxygen, silicon and aluminum. Iron ores have a wide range of formation in geologic time as well as a wide geographic ...
· The origin of giant Kirunatype iron ores has been debated for nearly 100 years. This study employs extensive stable isotope data from Kirunatype ores worldwide .
Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...
· Introduction. Many are familiar with the platinum group element and chromiterich rock sequences, and vanadium magnetite layers of the Bushveld Igneous Complex, South Africa, which make up the world's largest deposits of these elements. But few know that a rocks known "anorthosites" compose significant portions of these layered mafic intrusions (LMI).

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
One of the world's best Magnesite deposit occur in the State. The major deposits occur in Chalk Hills of Salem district. The reserves is estimated as million tonnes. It is used mainly for refractory purposes and in chemical industries.

VANADIUM RESOURCES IN TITANIFEROUS MAGNETITE DEPOSITS BY R. p. FISCHER ABSTRACT Titaniferous magnetite deposits are magmatic accumulations of magnetite and ilmenite. They commonly contain to 1 percent V 2 0 5, most of which is concentrated in the magnetite, and they have become the world's principal source of vanadium.
There are enough platinum group element deposits in the Bushveld Complex in South Africa to supply world demands for many decades or even a century using current mining techniques. Demonstrated reserves and resources published by mining companies make detailed calculations up to a maximum of about twenty years ahead, but there is abundant and adequate geological evidence that these deposits .
· 1. Introduction. The Batu Hijau porphyry copper–gold deposit is situated in Sumbawa Island, Indonesia ().It is a worldclass deposit of copper and gold, containing mineable reserves of 914 million tonnes grading % Cu and g/t Au (Clode et al., 1999).Copper and gold mineralization is closely related to the emplacement of tonalite porphyries (Mitchell et al., 1998; .
