However, this may also involve the ability of the HM to yield high value mineral recoveries of high purity with reduced/minimal number of beneficiation process steps, reduced energy consumption, minimal by-products and environmental pollution, as well as its scalability from laboratory or small scale to commercial or industrial scales.
The term 'mineral beneficiation' is generally defined as a value adding process on minerals from extraction to refining to production of the final consumable good. The history of mineral beneficiation goes to as back as in the 10th century when minerals were discovered and were at times used as a medium of exchange before the
Monazite is a by-product of extracting ilmenite, rutile, ... RE ores are generally associated with other minerals, so beneficiation processes are essential to adopt. The design of innovative processes combining flotation, gravity and magnetic separation is the focus of research. According to the nature of RE ores, rational …
