four statements made by the ceo and c/man lyc, page-45

imho, strongly suggest you don't introduce foreign comparisons here as you're well aware they are very unacceptable elsewhere, even for comparative purposes. Little late to be rewriting the rule book.

A simple Google search will give you a wealth of information plus many avenues to pursue:

As a rule of thumb (Jantimot could no doubt confirm/express better) the further down the scale you go the more complex and expensive separation becomes. Not really an issue at the LAMP as it is only designed to separate the LRE, both individually and from the SEG & HRE, which Lynas originally suggested would be toll processed elsewhere for onsale, but may not now be the case. I could speculate that something may develop here that will rock established wisdom but it's in plain view and I've dropped enough hints already.
