"The companies know they are being watched by Chinese sources so that copy cats will have wasted weeks playing around with sulphate mixes discovery issues that you raised here. I doubt if all is being disseminated to us by RBW and the recipe will be protected by patents and know how as other competitors try and figure away to do it."
There is nothing new about RBW technology that is of interest to discuss. Extraction of 65% REE, as well as continuous ion chromatography, is a technology 20 years ago.
At the moment, technology exists that allows us to extract 95-98% REE from phosphogypsum, and to carry out the process of obtaining individual REE compounds from the solution stream.
At the same time, the cost of REE extraction is less than $2 per kg.
