Summary:
Trail Operations is an integrated zinc refining and lead smelting operation that produces zinc, lead, silver. It also produces a variety of precious and specialty metals, chemicals and fertilizer products.
The zinc refinery consists of six major metallurgical plants, one fertilizer plant and two specialty metal plants. Depending on the mix of feeds, the facility has an annual capacity of approximately 300,000 to 310,000 tonnes of refined zinc. Zinc concentrates are initially treated in either roasters or pressure leach plants where sulphur is separated from the metal-bearing solids. The zinc is put into solution where it is first purified to remove other metal impurities and then electroplated onto cathodes in an electrolytic refining plant. The zinc cathodes are melted and then the zinc is cast into various shapes, grades and alloys to meet customer requirements. Other valuable metals, including indium and germanium, are also recovered as coproducts in the zinc plant. The ........
