KDR had about 50Mt worth also when you take into account ownership. So approx $16mil/Mt

CDL would have 100Mt presuming AVZ 50% ownership.

If prices have doubled (being conservative I don't think quadriple price are here to stay, especially since Manono comes online) would bring to $32mil/Mt.

Which would give $3.2 Bil as you also arrived at.

Although wouldn't be giving China a Africa discount cause they seem perfect happy doing business there.
