    What is Bauxite... How do we mine... etc
    http://www.riotinto.com/whatweproduce/452_aluminium_3530.asp

    Bauxite
    Bauxite is the mineral form of aluminium, occurring naturally in the earth's crust, and containing about 50 per cent alumina. It is formed by the weathering of sedimentary rocks which contain a high proportion of aluminium-bearing minerals. Bauxite is normally found in a layer averaging three to five metres deep, located about half a metre beneath the topsoil. Mined bauxite resembles small red pebbles, called pisolites, averaging about five millimetres in diameter.

    Mining and processing bauxite
    Bauxite exists in free-flowing form, which makes it relatively easy to dig out of the ground. Front end loaders load the bauxite into 150 tonne bottom-dump trucks, which take the ore to a dump station for transportation to the processing plant (called a beneficiation plant) by rail and belt conveyor.

    At the beneficiation plant, the bauxite is screened and washed to remove fine particles. It is then placed on stockpiles, which are loaded onto ships....

    "Bauxite prices may gain 30% next year on the back of rising demand in China and dwindling Indonesian exports. Prices may rise as high as $65/t, including insurance and freight, Chetan Shah, managing director of Ashapura Minechem Ltd., India`s largest exporter of bauxite, said in a telephone interview yesterday in Mumbai.

    "The landed cost of bauxite increased 68% in 2007. The Chinese government also announced in late 2007 that they will impose a 15% Export Tax on all bauxite shipments from China effective January 1, 2008. There was no Export Tax on refractory grade bauxite in 2007. New pricing being quoted for bauxite is now over 100% higher than the end of 2007!!

    BROWN FUSED ALUMINA (BFA)
    July 2007 prices of BFA were in the range of $365 - $375/ton and escalated to $380 -
    $400/ton in August 2007. By early September, price levels had reached $550 - $600/ton. It is being reported that by the second quarter of 2008, prices will escalate to $750 - $775/ton range, an increase in price of 112% since July of 2007 to June of 2008."

    "Spot imported bauxite prices had risen to nearly $80 per dry tonne versus $70 to $75 in September and $60 in August, due to strong Chinese demand and high freight costs, traders said.

    One trader said some term Indonesian bauxite for 2008 shipments to China had been set at about $18, based on free-on-board, versus around $17 this year."

    "When delivered to Chinese ports, the 2008 term price would rise above $70, based on current freight charges, compared with about $44 for term shipments this year. "

    "Industrial Minerals (2000b) quoted end-of-year prices for
    several types of imported refractory-grade bauxite from China
    and Guyana. The price quotes for Chinese refractory-grade
    bauxite, minimum 87% Al2O3 free on board (f.o.b.) Chinese
    ports, were as follows: Shanxi, shaft, lump, $71 to $75 per ton;

    Shanxi rotary, lump, $85 to $90 per ton; and Guizhou, round,
    lump, $70 to $73 per ton. The price ranges for Guyanese

    "Total US$/tonne 20.58

    A value of US$ 32 per tonne was assumed for the bauxite product. This value was
    selected to produce a positive cash flow and a positive net present value (NPV)
    at a discount rate of 7.5 percent. The internal rate of return (IRR) is 9.0
    percent at US$ 32 per tonne. At a value of US$ 30 per tonne, both the NPV at
    7.5 and 5.0 percent become negative and the internal rate of return (IRR) is 3.0

    "Take bauxite. Only a small quantity of bauxite, as raw material for aluminium, is sold in Indian markets, because most aluminium makers have captive mines. In the international market, bauxite is priced at US $100 per tonne (over Rs 4,000), while in India, the estimated cost to mine bauxite is Rs 225 per tonne. The price of aluminium in the global market is US $2,680 per tonne—over Rs 1,00,000 as per June 20, 2007. Indian companies can make a killing in this market with their captive bauxite mines. This explains the aluminium rush to Orissa. "

    "Aluminum is the second most common element in the earth’s crust after silicon. The vast majority of today’s supplies are obtained from bauxite ores, which occur widely in the tropical regions, and are low cost to mine. Typical bauxite mining costs are only $5-10/t. Compared with other forms of mining, bauxite extraction is relatively simple. Most operations incorporate progressive land rehabilitation and re-vegetation programs in order to minimize environmental impact. There is no likelihood of bauxite resource depletion in the foreseeable future. "
