No, its a simple process actually ... dont compare it to ARU! That is a different beast ... they have to separate the different rare earths then the phosphate, then the uranium!!!

Phosphate on its own has been widely used to extract uranium over the years ... Some info from Wise:

URANIUM RESOURCES IN PHOSPHATE ROCK
The world average uranium content in phosphate rock is estimated at 50 - 200 ppm. Marine phosphorite deposits contain averages of 6 - 120 ppm, and organic phosphorite deposits up to 600 ppm.
World uranium resources in phosphate rock are not very well known; the following table shows approximate inventories.

URANIUM RECOVERY
The widely used sulphuric acid process concentrates most of the uranium in the product stream (fertilizers, detergents, etc.).
Various technologies exist to recover the uranium from the product stream, based on solvent extraction:
DEPA-TOPO (also DEHPA-TOPO, D2EHPA-TOPO)
uses di(2-ethylhexyl) phosphoric acid and trioctyl phosphine oxide as extractants (ORNL process)
OPAP
uses octyl phenyl acid phosphate as extractant (ORNL process)
OPPA
uses octyl pyro phosphoric acid as extractant (Dow process)
The DEPA-TOPO process has proven to be the best technology available, according to [IAEA 1989]. It comprises the following steps:
1. Acid preconditioning and gunk removal
2. First cycle extraction and strip
3. Raffinate post treatment
4. Second cycle extraction, strip and uranium precipitation
Worldwide, there are approximately 400 wet-process phosphoric acid plants in operation from which some 11,000 t U could in principle be recovered each year, according to [IAEA 1989]
A more cautious figure of up to 3700 t U/a for the theoretically possible uranium recovery from phosphates is presented in [IAEA 2001]. This total assumes annual production of phosphate rock of 142 million tonnes per year yielding 66 million tonnes of concentrate. Marine phosphorite deposits account for 80% of the world output of phosphate based fertilizer products, and 70% of this total is converted into wetprocess phosphoric acid, the base for the current uranium extraction process. Assuming an average recoverable content of 100 ppm of uranium, this scenario would result in an annual output of 3700 t U/a. [IAEA 2001]
Eight plants for the recovery of uranium from phosphoric acid have been built and operated in the United States since 1976 (Florida: 6, Louisiana: 2). Plants have also been built in Canada, Spain, Belgium, Israel, and Taiwan, see Facilities for Uranium Recovery from Phosphate.
