· Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. The answer is B, bauxite . Explanation: New questions in Biology. A biologist .

Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly...
Once extracted from the bauxite, pure aluminum is often much too soft and ductile for commercial use. For this reason, aluminum is almost always combined with other alloying metals or elements. These commonly include copper, magnesium, manganese, silicon, tin, and/or zinc.
Bauxite is the only ore containing 2025 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide. It is because of the iron from where bauxite gets its deep ...
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard brittle silvery metal, often found in minerals in combination with is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber ...
Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and .
Coal, bauxite, chromite, iron manganese ore and limestone almost contributed 99% of the total value of mineral production. The state is gifted with large reserves of bauxite, chinaclay, chromite, coal, dolomite, fireclay, graphite, gemstones, iron ore, limestone, manganese ore, mineral sand, nickel ore, pyrophylite and quartz. The rich mineral wealth of the state is attributed to its ...
· Metal ores are generally oxides, sulfides, silies (Table 1) or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust, or "noble" metals (not usually forming compounds) such as gold (Figure 1 ). The ores must be processed to extract the metals of interest from the waste rock and from the ore ...
Aluminum is extracted from bauxite, a rock composed mainly of aluminum oxide and aluminum hydroxide minerals. The rock usually includes other materials such as iron hydroxides, clay, silt, and free silica. It most often occurs as a residual soil material in tropical and subtropical areas. It is the primary source of aluminum. Bauxites are typically classified according to their intended ...
The major impurities in Bauxite are iron oxides (goethite hematite), silicon dioxide, the clay mineral kaolinite as well as small amounts of anatase (TiO2). Consequently, its composition varies considerably with alumina constituting from about 50% to about 70%. Also know, How bauxite is extracted? Aluminium ore is called bauxite.

· Manganese is an element symbolized with "Mn" which exists naturally as an ore. Manganese has a huge demand globally due to its essential appliions, with the metal being used in the production of steel as well as in the manufacturing of highcapacity batteries. About million tons of manganese are produced around the world each year. The Kalahari Desert is thought to contain .
The position is particularly advantageous in metallic minerals of the ferrous group, including the ores of iron, manganese, chromite and titanium. India's reserves of mica and bauxite also are rated among the largest in the world. The country not only is selfsufficient in the production of these minerals, but also exports large quantities every year.
