With the worldwide selloff  in commodities, speculators are short selling metals causing  great turmoil in the metals and mining sectors.    The depressed demand for aluminum and other basic raw materials is taking its toll on both the top and bottom lines of the major suppliers as well as the revolving door to the executive office.  The LME (London Metals Ex) has recently receded to $1830/ton, down $670 from the $2500/ton level  in 2011 and $3000/ton in 2008-9.
