I don't see this as a comparative advantage.

The cu-mo mines get the moly for free in the first place.
Some still have not added roasting to get the moly as moly
price had been too low.

The byproduct moly from these mines has shifted production
so it is now mostly from cu mines in recent years as they have
added roasters.

So production is going the other way, not back to primary mo.

But it is dependent on cu need. If that were to fall then
the primary mines would benefit. But I don't see that.

hey! no matter what you are paying 5 dollars a lb for roasting these days copper or no. Maybe more.

Copper and pyrite is got out through leaching a priori roasting. It costs a tad more, but not much.
