The $1.2 billion sale by Swiss German chemical company BASF of its stake in K+S could trigger a battle amongst global mining giants for the German potash miner.

BASF sold its roughly 10 percent stake in the company as part of a shift away from the nitrogen fertilizer business in the face of competition from lower-cost producers in the Middle East. If Russian fertilizer company EuroChem sells its own K+S stake of 14% it could push the German miner into play, with majors such as BHP, Vale and Rio Tinto amongst the potential buyers.
