what to do with residue...think tank...outside the box., page-8

As far as I can tell the offending waste is the LWP residue that contains 1650 mg/Kg uranium and 22 mg/Kg thorium. The uranium content is not insignificant and therefore this 'waste' could be viewed as a valuable.

Lynas has about 450,000 tonnes ofthis LWP residue that is essentially contaminated gypsum. It generates about 32,000 tonnes of this crap per year.

If that gypsum has a U concentration of 1655 mg/Kg and a Th concentration of 22 mg/Kg, thenthis represents about 876,000 Kg of U3O8 (105 m3). At current spot prices that amount of U3O8 would fetch about $56million dollars.

Although I have no specific knowledge of the LAMP flowsheet, it seems to me that it wouldn't be so difficult  or costly to introduce a secondary circuit to dissolvethat WLP gypsum residue, strip out all the U and Th out using an appropriateion exchange material (plenty of options here) and then elute the resin to recover the uranium. Alternatively, why not take U and Th out upstream.

Clean stripping of U and Th would produce a decontaminated gypsum that nobody could object to even in Malaysia and Lynas might even be able to recover costs.
