"simple" is hardly relevant, cost effectiveness is the key metric, to produce a "concentrate" with the highest proportion of the more valuable REE at the lowest cost possible.

As Shenghe have obviously done some great work lifting the cost effectiveness of GGG con, conveniently as a chloride neatly backloading reagent, so has Lynas greatly improved the cost effectiveness of their concentrate operation @ Mt Weld, currently setting it up for considerably expanded volumes. The big resource update due very shortly will not doubt also contain some detail on process work for the new ore zones which may be instructive.

Recoveries are a key economic all the way thru the process from beneficiation all the way thru to finishing, particularly main revenue stream NdPr, the second would be placement to mkt, realisation of premium value add. GGG business plan appears focused on only retaining some influence over the primary stages of mine & concentrate, certainly nothing put forward here suggests otherwise.
