Nah, it's a pun.

Inside the facility on the right side there's a window to an inaccessible room with an overhead rail and 2 big vats of fluids. Parts of Orokin bio-wall are being transported in and dipped in the vats, the liquid being some kind of acid that burns away all of the organic material, exposing the gold framework. In this case, "enrichment" literally means making Nef rich(er).
