Resources Victoria geoscientists have found weathered granite could help support renewable energy technologies.
Research by the Geological Survey of Victoria (GSV) has identified elevated concentrations of the right minerals to produce high-purity alumina in clays formed from granite rocks in central Victoria.
High-purity alumina is on the Australian Critical Minerals List and can be used to help produce renewable energy products like lithium batteries and low energy lighting.
The discovery is highlighted in a report by GSV characterising some of the state's known critical minerals opportunities and is part of the Developing Victoria's Critical Minerals initiative.
The study examined clays from active and former mines in central Victoria. This information was complemented with samples from the GSV Drill Core Library and field samples from clay outcrops from western and central parts of the state.
In addition to their potential use in renewable energy, clays in Victoria have everyday uses, including the manufacture of paint, paper, bricks, cosmetics and medicines.
