A CESL plant can be located on-site, eliminating the costs associated with shipping concentrate to a smelter. The savings in shipping costs allow for the ability to process a lower-grade concentrate. The result can be a significant increase in overall metal recovery, enhancing the economics of the mine.
Another advantage of the CESL Process is that bulk concentrates (eg. Cu-Zn, Cu-Ni) can be processed to recover all payable metals. There are many instances where production of a bulk concentrate would enhance overall metal recoveries as opposed to separation of the minerals into two or more concentrates in which the minor component is not paid for, and in some cases, penalized by the smelter.
