zircon mine in the world
Indigenous employment in 2023


The Jacinth-Ambrosia operation in South Australia is the world’s largest zircon mine. Iluka discovered the Jacinth-Ambrosia deposit in 2004 and commenced production in 2009. 

The operation encompasses mining and wet concentration activities, with capacity to process up to ~120 tonnes per hour of heavy mineral concentrate. This heavy mineral concentrate is then transported to Iluka's Narngulu mineral separation plant in Western Australia for final processing. 

Jacinth-Ambrosia is South Australia’s first mining development in a mixed use regional reserve (the Yellabina Regional Reserve). The operation is recognised by the South Australian Government for its levels of Indigenous employment and commitment to environmental management.
