Rio Tinto says miners need to leverage technology as scrutiny of the industry rises

Mining companies should make more use of technology to respond to increasing demands from investors and communities for responsible mining practices, Rio Tinto CEO Jean-SĂ©bastien Jacques said on Monday.

Technologies such as autonomous rail-cars and increased automation can lower the impact of the industry on the environment as well as raise profit margins, he said, adding that blockchain can be deployed to track if the supply chain met ethical standards.
