Depressing pyrite in selective flotation of complex polymetallic ores

点击翻译按钮获取中文摘要

This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and metal extraction efficiently and economically. These technologies may provide value in processing low quality complex polymetallic resources using low quality water, whilst halving the operating costs of mineral concentrators and providing corresponding reductions in harmful emissions.
