WA Kaolin has an established Ore Reserve Estimate (JORC 2012) of more than 64 million tonnes1 of extremely high-grade, easy access kaolinite at a site near the town of Wickepin, 220km southeast of Perth, Western Australia. ... WA Kaolin developed the K99 dry process in a working pilot plant in Kwinana, Western Australia, with a capacity of ...
This paper focused on describing the mineralogic and geochemical processes leading to the occurrences of the REE from mined kaolins together with the REE from mine …
The large concentrations of REE were obtained by separating the dense heavy minerals from the coarse fraction (grit) obtained during the typical production of kaolin-group minerals (kaolinite) from kaolin ore. The amount of zircon (estimated from the 6–11 wt.% Zr) and the absence of monazite did not explain the high concentrations …
