Rio Tinto CEO’s Big Test: What to Do With Lithium

Rio Tinto last year bet big on lithium. Its new chief executive officer will next week set out whether the commodity has a prominent future at the world’s second-largest mining company.

Simon Trott, who took charge of Rio Tinto in August, has promised changes that analysts speculate could include asset sales, cost cuts and slower developments. On Thursday, he will lay out a detailed vision for the company for the first time at an investor gathering in London.
