The Flotation Separation of Magnesite and Limonite Using ...

In order to reduce the iron impurities in magnesite ore and improve the purity of magnesium products, the difference in floatability between magnesite and limonite has been studied by using mixtures with a collecting agent—KD (cationic amine collectors, containing soluble components). Sodium hexametaphosphate, pH, sodium silicate, and sodium carboxymethyl cellulose were used as regulators.

The Flotation Separation of Magnesite and Limonite Using ...

Magnesite and Limonite. The collector KD was 150mg/l, and the pH value of pulp was adjusted. Flotation tests were carried out on single minerals of magnesite and limonite at different pH values, and the difference of the pH value of these two minerals in the system of the amine collector was studied. The test results are shown in Figure 4.

Limonite - Mining Fundamentals

Limonite is an iron ore, containing a hydrated iron (III) oxide-hydroxide mixture in different compositions. It is one of the two major iron ores, the other being hematite - used in the production of iron. It was named by Johann Friedrich Ludwig Hausmann in 1813 after the Greek word for meadow, indicating its common occurrence in lowlands.

Manganese nodule - Wikipedia

The mineral composition of manganese-bearing minerals is dependent on how the nodules are formed; sedimentary nodules, which have a lower Mn 2+ content than diagenetic, are dominated by Fe-vernadite, Mn-feroxyhyte, and asbolane-buserite while diagenetic nodules are dominated by buserite I, birnessite, todorokite, and asbolane-buserite. The growth types termed diagenetic and hydrogenetic ...

Magnetite Lodestone Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. Silicate type (or saprolite type) nickel ore formed beneath the limonite ...
