Flotation is an important process in the minerals industry, which underpins Australia's prosperity. Ore is first finely ground and suspended in water. Finer grinds need more energy. The energy used in grinding in Australia is 14 percent of the national electricity consumption. This project will lead to a flotation technology that can successfully process much coarser particles than current devices, with large savings in grinding energy, greenhouse gas emissions and water consumption. A case study of a large mine shows that, by increasing the initial grinding size from 100 µm to 500 µm, the new technology could cut grinding energy by 45 percent, the carbon dioxide emissions by the same amount, and the water consumption by a factor of five.

浮选是矿业的一个重要过程，是澳大利亚繁荣的基础。矿石首先被细磨并悬浮在水中。更精细的研磨需要更多的能量。在澳大利亚，用于研磨的能源占全国电力消耗的14%。该项目将产生一种浮选技术，该技术可以成功地处理比现有设备更粗的颗粒，大大节省研磨能源，温室气体排放和水消耗。一个大型矿山的案例研究表明，通过将初始磨矿粒度从100微米增加到500微米，新技术可以将磨矿能耗降低45%，二氧化碳排放量减少相同数量，水消耗量减少五倍。
