Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.56 It is the most magnetic of all the naturally-occurring minerals on Earth.57 Naturally-magnetized pieces of magnetite, called lodestone, will attract small ...
niobium resource in the center of the ECCC hosted by an unusual magnetite-dolomite carbonatite rock (Mariano, 1978). Magnetite and dolomite are the major rock-forming minerals in this rock lithology, with minor ilmenite, rutile, biotite, quartz, and pervasive barite alteration. The magnetite-dolomite carbonatite exhibits several different textures

Chengde chromium-bearing vanadium–titanium magnetite (CCVTM) has been used as an important mineral resource in sinter making. The MgO content of this sinter can be enhanced by adding dolomite, which improved operation of the blast furnace. The effects of MgO in the form of dolomite on metallurgical properties, microstructure and mineral compositions of CCVTM sinter were studied by a …
Mar 30, 2020 When magnetite is added to a concrete mix, it produces heavy concrete, which is twice as dense as standard concrete. Heavy concrete is widely used in buildings that require protection from radiation, such as nuclear power plants, X-ray facilities and uranium mining sites.
The first recorded mining was in 1919 but the main period of activity was from 1940 to 1955 when F.H. Faulding & Co. Ltd extracted 6000 t for pharmaceutical and chemical use. The deposit comprises 60 magnesite beds, 0.05–3.0m thick, over a strike length of 1.5km within the upper 300m of the Skillogalee Dolomite.
Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone
Zones: 1—magnetite-chlorite-dolomite, 2—chloritolite, 3—serpentinite with carbonatization and chloritization, 4—antigorite serpentinite. (a) The central zone (2) is composed of nearly equal amounts of carbonate and magnetite and a minor amount of chlorite, the content of which increases in the marginal parts of the zone.

In vein calcite and dolomite carbonatites, as well as magnetite-dolomite-phlogopite-serpentine rock, magnetite contains mainly oxy-exsolution lamellae of ilmenite (predominantly) or geikielite. As was shown in [ 16 , 40 ], magnesium is the main subordinate component in magnetite of the Kovdor phoscorite-carbonatite complex.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
The global dolomite mining market size was valued at USD 1.73 billion in 2019 and is expected to grow at a compound annual growth rate (CAGR) of 3.8% from 2020 to 2027. Rising consumption of dolomite as an aggregate for construction applications as well as an ingredient in cement manufacturing is the major factor supporting the market growth.
