BHP Billiton Ltd, Rio Tinto Ltd, Brazil`s Cia Vale do Rio Doce (CVRD) and OAO Russian Aluminium mining companies are considering bids for aluminium producer Alcan Inc to prevent Alcoa Inc from acquiring the company, the Sunday Telegraph reported, citing industry executives.
Private equity company TPG may also be interested in playing a "role in any breakup" of the US$33 billion Alcoa-Alcan deal, the paper said.
A combined Alcoa-Alcan would control about 25% of the alumina raw material and primary aluminium markets, the paper said.
