The company completed the sale of its remaining coal assets in Queensland for $3.95 billion this week.
The transactions include the sale of Rio Tinto's interests in the Hail Creek coal mine and Valeria coal development project to Glencore for $1.7 billion, and its interest in the Kestrel underground coal mine to a consortium comprising private equity manager EMR Capital and PT Adaro Energy Tbk for $2.25 billion.
Rio Tinto CEO Jean-Sebastien Jacques said the sale of the remaining Australian coal assets delivered exceptional value to its shareholders.
"Once again, I would like to thank the many people across Rio Tinto and the communities in which we operate who have contributed to the coal business," he said.
"I wish them continued success under new ownership."
To reflect the sale of the assets, Rio Tinto's 2018 production guidance is updated to 4 million tonnes of hard coking coal and 2.5Mt of thermal coal.
