Ivan Glasenberg, the chief executive of mining and trading giant Glencore International, landed the deal of a lifetime in 2012 by orchestrating the takeover of mining company Xstrata. The deal still faces hurdles but once it's final--the closing is expected by March 15--Glasenberg will emerge as the new company's CEO and second-biggest shareholder after the emirate of Qatar.
