you still haven't done any research obviously. It shows immediately as you keep saying "downblending"! That's not what this is. Silex stands for Separation of Isotopes with Laser EXcitation.
It increases the encirclement, not decreases (as would be the case in downblending).
And as for profitability, re-read my earlier comment and do this back of envelope math - Silex process ALL IN cost for UF6 using Tails is <$30 USD per lb.
Market prices are
U3O8 lb = $80 USD
Conversion to UF6 lb = $30 USD
That's $110 USD revenue per lb, minus cost at <$30lb = profit of $80lb - on 5 million lb's per annum for 30 years just using the Paducah tails.. Quite confident "going bankrupt" isn't in that scenario, and that doesn't include the profit from additional enrichment, or zero spin silicon, or medical isotopes

Anyway, your loss. Just trying to help out those who might be interested in a factor that will be impacting the situation for Uranium mining.
