About Rio Tinto

Every idea, every innovation, every little thing the world calls ‘progress’ begins with a first step, and someone willing to take it: explorers, inventors, entrepreneurs. Pioneers.

For nearly 150 years, Rio Tinto has been a company of pioneers – generations of people spanning the globe, all with the grit and vision to produce materials essential to human progress.

Our iron ore has shaped skylines from Shanghai to Sydney. Our aluminium – the world’s first to be certified “responsible” – helps planes fly and makes cars lighter. Our copper helps wind turbines power cities and our boron helps feed the world, and explore the universe. Our diamonds help us celebrate the best parts of life.

Where you’ll be working

Our Gove Operations have been supplying the global aluminium industry with world-class bauxite for more than 40 years. Located in Australia’s Northern Territory, each year the operation produces approximately 12 million tonnes of bauxite.

With a workforce of 460 people, daily activities include mine operations, maintenance, asset management, shutdown planning and execution, export operations, cultural heritage management, and closure activities following our decision to close the site’s alumina refinery and associated Residue Disposal Area in 2017. 

We expect our bauxite mining operations on the Gove Peninsula will cease in 2030 and we are undertaking significant work to support closure of the operation. We also recognise our operations take place on Indigenous-owned land, and we are committed to working together to achieve a positive future for Nhulunbuy and the Gove Peninsula post-mining.
