Feldspar mineral (sand) and high pressure carbon dioxide can be used to produce alumina. CaAl_2Si_2O_8 + 2CO_2 +4H_2O > CaCO_3 + 2SiO_2 + 2Al(OH)_3 High temperature proceses. Kaolin clay is composed of aluminum and silicon (Si2Al2O5(OH)4). Reduction of Kaolin would then result in an aluminum/silicon alloy.

Silicon dioxide, a major constituent of sand, is a network of silicon oxygen bonds. The less polar, or more oily compounds will have less attraction to the polar silica, and come off of the column first.

EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.

Silicon compounds are the most significant component of the Earth''s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semimetallic or metalloid, because it has several of the metallic characteristics.

Because sand is still very cheap – sand itself is freely accessible; only extraction costs need to be covered – there is little or no incentive to induce a change in consumption. The UNEP report therefore suggests striving for a better pricing and taxation of sand extraction so that alternative building materials to sand, such as recycled building material or glass, become economically viable.

A roller bed and rotary endoverend shaker were compared for the extraction of mineral N from a variety of soil types; both were equally efficient with an optimum extraction time of 30 min. However, the roller bed permitted a greater operational capacity, a faster throughput of samples, and easier identification of sample bottles compared with the endoverend shaker.
