Beneficiation of phosphate ore is a process which includes washing, flotation and calcining. Froth flotation is used to concentrate the mined ore to rock phosphate. The mined ore is crushed and washed, creating a slurry, this ore slurry is then treated with fatty acids to cause calcium phosphate to become hydrophobic.

We process some of our ores to increase the concentration of target minerals or remove unwanted components using processes such as ...
The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn …
The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that together, might enable lunar habitation.The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration …

India has large reserves of Iron ore, Bauxite, Chromium, Manganese ore, Baryte, Rare earth and Mineral salts. India has vast mineral potential with mining leases granted for the longer and stable tenure of 50 years. Consumption of steel has increased in the rural India from 19 Kg in 2019-20 to 21.5 kg per capita for the year 2020-21.
The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6).
Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the least dense metal and the least dense solid element.Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such …
Operations. Cleveland-Cliffs manages and operates four iron ore mines in Minnesota and two mines in Michigan, one of which, the Empire Mine, has been indefinitely idled. These mines produce various grades of iron ore pellets, including standard and fluxed, for use in blast furnaces as part of the steelmaking process as well as Direct Reduced (DR) grade pellets for …

Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. 3.19.1.1.2 Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.
Iron Ore. Iron ores are rocks and minerals from which metallic iron can be extracted.; India has large iron ore reserves.

Even 50% extraction from the ore will be economical due to high price of HREE. As the area is well exposed and outcrops have high relief, the cost through opencast mining will be minimum (Bhushan and Somani, 2019). 4.1.2. Residual deposits. Residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold deposits.
