The new groups include aluminum, copper and coal, diamonds and minerals, and iron ore.
Rio Tinto’s coal operations and the existing copper portfolio will be copper and coal product group and will be led by Copper CEO Jean-Sébastien Jacques.
The diamonds and minerals product group, which will include uranium, will operate under the supervision of CEO Alan Davies.
Other key corporate functions will also be restructured to reduce costs and improve effectiveness.
Rio Tinto chief executive Sam Walsh said: "These changes are part of our continuing business transformation to reduce costs, simplify and strengthen our company and deliver sustainable value for shareholders.
"Our coal and uranium assets remain a part of our world-class portfolio.
"We will work hard to ensure there is a smooth transition for our colleagues in the Energy product group and continue to maximize efficiencies in our coal and uranium operations."
