Linklaters, Slaughter and May and Herbert Smith have all advised on Rio Tinto’s $15.2bn (£9.5bn) rights issue and joint venture with one-time merger partner BHP Billiton.

The roles come in the wake of this week’s collapse of Rio’s $19.5bn (£12.1bn) deal with Chinese resource giant Chinalco, with Rio opting against a tie-up after shareholder concerns that the deal was not in the best interests of the mining company.
