Conflicting market signals continue to cloud the outlook for battery metals, especially lithium, with Rio Tinto, one of the world’s biggest miners, pushing ahead with a $6.7 billion acquisition, just as a leading Chinese producer struggles to sell lithium.

Arcadium Lithium said on Monday its shareholders have voted in favor of a $6.7 billion sale to Australian mining giant Rio Tinto. Shares of Arcadium Lithium rose about 7% in extended trading after the company said that about 98% of its shareholders had voted in favor of the sale.

Rio Tinto PLC RIO shares inched up 0.51% to £46.92 Monday, on what proved to be an all-around favorable trading session for the stock market, with the FTSE 100 Index UKX rising 0.22% to 8,102.72. Supported by world-class markets data from Dow Jones and FactSet,
