Thermal Treatment Strategies:
Processing Approach at Tranbreez
To mitigate the challenges associated with silica gel formation and to enhance REE extraction, thermal pretreatment methods such as selective roasting or "fuming" have been explored. These processes aim to decompose non-REE-bearing phases and stabilize silica, thereby improving leaching efficiency. For instance, roasting eudialyte concentrates at temperatures ≥750 °C can decompose sulfates of zirconium, hafnium, and other elements, while maintaining REE sulfates in a soluble form.
Processing Approach at Kvanefjeld
This approach enables the extraction of REEs without the need for complex, high-temperature, chemically aggressive mineral cracking stages.Such a method simplifies the processing flow sheet and can lead to cost efficiencies.minedocs.com
