Extending the range of the flotation process for particle separation

点击翻译按钮获取中文摘要

The minerals industry is a significant contributor to Australia's prosperity. Flotation is an important process for upgrading low-grade ores to high-grade concentrates, and for recovering fine coal from tailings. This project is aimed at solving a long-term problem in current flotation practice, the difficulty in recovering ultrafine and coarse particles, currently lost from production. We will pursue two new discoveries recently made by us, relating to the recovery of ultrafines and coarse particles. Benefits to Australia are of the order of $500 million a year in increased exports, education of high-quality graduates, export income from license fees and equipment.
