Metals Insider reported that Australian technology supplier Ausmelt has signed a licensing agreement with Korea Zinc for the construction of two new Ausmelt technology furnaces at the company’s Onsan zinc complex.

Korea Zinc already operates ten Ausmelt technology furnaces at Onsan, treating a range of zinc slags and residues as well as secondary lead and copper materials. The two new furnaces will be built at Onsan to recover lead and zinc from up to 120,000 tonnes per annum of zinc leach residues.
