What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary rocks.They formed from chemical reactions that combined iron and oxygen in
Silicon dioxide (SiO2), silicon's most common compound, is the most abundant compound in the earth's crust, and comprises roughly 14% of the earth's crust. SiO2 is mined both as sand and as vein or lode deposits, for use in industry.

Bauxite 101 Bauxite ore is the worlds main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide.
Second only to oxygen, silicon is the most abundant element in Earth's crust. It is found in rocks, sand, clays and soils, combined with either oxygen as silicon dioxide, or with oxygen and other elements as silicates.

Aluminum is a silver-white metal and is very light in weight (less than three times as dense as water) yet strong. Because aluminum is ductile, it can be drawn into wires or pressed into sheets or foil.
The technique for silica mining depends on the location of the silica. Sand, the most common and readily available source of silica is found in beach and basin deposits, large dunes in desert areas, underground in glacially deposited pockets, and in sandstones.

rocks are confined to the Earths crust, which is the thin, light outer solid skin of the Earth ranging in thickness from 40100 kilometres (25 to 62 miles) in the continental blocks to 410 kilometres in the ocean basins.
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily
Iron (Fe) is one of the most abundant rock-forming elements, constituting about 5% of the Earth's crust. It is the fourth most abundant element after oxygen, silicon and aluminium and, after aluminium, the most abundant and widely distributed metal.
