The mine complex has a history of close association with Nyrstar's Clarksville smelter which was originally constructed to treat concentrate from the mine complex. Once operations are recommenced, the mine complex will continue to be an important source of concentrate for this smelter providing (approximately) 50% of its concentrate requirements.

A hydrometallurgical process has been developed for the recovery of valuable metals from the flue dust of a copper smelter. The dust containing various metals, such as lead, zinc, copper, bismuth, indium, cadmium, iron, arsenic etc., was treated using this hydrometallurgical process to recover all these metals and also to solve environmental pollution problems.
First published on 3rd October 2013. The modes of action of the commercial solvent extractants used in extractive hydrometallurgy are classified according to whether the recovery process involves the transport of metal cations, M n +, metalate anions, MX x n −, or metal salts, MX x into a water-immiscible solvent. Well-established principles of coordination chemistry provide an explanation ...
