Mineral Processing an overview ScienceDirect Topics

Minerals Processing. A wide variety of minerals processing routes are used for REE deposits (Jordens et al., 2013; Krishnamurthy and Gupta, 2015). For many REE ores, processing techniques for the minerals are unproven on a commercial scale and processing is a major challenge that needs to be considered early in exploration.
