Iron(III) oxideWikipedia

2019-10-15 · Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry.

Iron(II,III) oxideWikipedia

2019-10-26 · Iron(II,III) oxide is the chemical compound with formula Fe3O4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe2O3) also known as hematite. It contains both Fe2+ and Fe3+ ions and is sometimes formulated as FeO Fe2O3. This iron

Mineral Resources in DesertsUSGS

Some mineral deposits are formed, improved, or preserved by geologic processes that occur in arid lands as a consequence of climate. Ground water leaches ore minerals and redeposits them in

titanium processingTechnology, Methods, & Facts

2019-10-29 · The predominate minerals are rutile, which is about 95 percent titanium dioxide (TiO 2), and ilmenite (FeTiO 3), which contains 50 to 65 percent TiO 2.A third mineral, leucoxene, is an alteration of ilmenite from which a portion of the iron has been naturally leached.

What's a uranium centrifuge?HowStuffWorks

2006-10-26 · Uran­ium is an element that is similar to iron. Like iron, you dig uranium ore out of the ground and then process it to extract the pure uranium from the ore. When you finish processing uranium ore, what you have is uranium oxide. Uranium oxide contains two types (or isotopes) of uranium: U-235 and
