© 2017 The Author(s). Current methodologies for the extraction of tantalum and niobium pose a serious threat to human beings and the environment due to the use of hydrofluoric acid (HF). Niobium and tantalum metal powders and pentoxides are widely us...

Towards large scale microwave treatment of ores: Part 1 – Basis of design, construction and commissioning (2017)
Journal Article
Buttress, A., Katrib, J., Batchelor, A., Jones, D., Craig, D., Royal, T., Dodds, C., & Kingman, S. (2017). Towards large scale microwave treatment of ores: Part 1 – Basis of design, construction and commissioning. Minerals Engineering, 109, https://doi.org/10.1016/j.mineng.2017.03.006

Despite over thirty years of work, microwave pre-treatment processes for beneficiation of ores have not progressed much further than laboratory testing. In this paper we present a scaleable pilot-scale system for the microwave treatment of ores capab...
