Risdon Zinc Works

Risdon Zinc Works (trading as Nyrstar Hobart) is a major zinc refinery located in Lutana, a suburb of Hobart, Tasmania, Australia. The smelter is one of the world's largest in terms of production volume, producing over 280,000 tonnes (280,000 long tons; 310,000 short tons) annually of high-grade zinc, primarily as die-cast alloys and continuous galvanising-grade alloys. These products are exported for global markets and utilised in a wide range of industries and products, from building and infrastructure to transportation, business equipment, communications, electronics, and consumer goods. The facility produces zinc using the Roast, Leach, Electrowinning (RLE) method, creating leach byproducts, including cadmium, gypsum, copper sulphate, lead sulphate, sulphuric acid, paragoethite and leach concentrate. The refinery has been owned and operated by the global multi-metals business Nyrstar since 2007. Nyrstar Hobart works closely with Nyrstar's Port Pirie multi-metals smelter in South Australia. The facility is Tasmania's largest exporter, contributing 25% of the state's overall export value in 2013.
