Trillions of bubbles at work for Australia

Graeme Jameson’s technologies use trillions of bubbles to add billions of dollars to the value of Australia’s mineral and energy industries.

Graeme took flotation, a century-old technology developed in Broken Hill, and transformed it. A turbulent cloud of minute bubbles are pushed through a slurry of ground-up ore where they pick up tiny mineral particles and carry them to the surface.

John Nutt helped design and analyse the sails of the iconic Sydney Opera House early in a career that saw him pioneer the use of computers in engineering, and contribute to the first fire code for buildings.

Kevin Galvin’s invention of the Reflux Classifier has generated hundreds of millions of dollars in benefits to the Australian economy, and revolutionised mineral processing around the world. It maximises mineral recovery by improving the recovery of fine, but still valuable, particles. Continue reading Making plastics, mining, and engineering

Bubbles capture minerals and toxic algae

A radical flotation technology has earned Australia over $4 billion in mineral exports each year by improving mineral particle recovery from wastewater.

Chemical engineer Graeme Jameson, AO, of the University of Newcastle, developed the technology, which was first used in mineral processing plants and is now being applied to other industrial practices.
