History

The Tomago plant was started in 1983 using Pechiney AP18 technology. Two potlines with 240 pots each were built and operated at 181 kiloamperes (kA) for a production of 240,000 tonnes per year. In 1993, a third AP18 potline with 280 pots was commissioned. After potline 3 start up, current on the three potlines was 182 kA for a production of 385,000 tonnes per year. In 1998, the potlines 1 and 2 were extended with 20 pots at the end of each room, making 280 cell per line. The production of Tomago was increased by 50,000 tonnes to 435,000 tonnes per year. In 2002 the plant commenced the AP22 project to reach the a line current of 226 kA in 2007. [3]

As at 2017, it is the largest consumer of electricity in New South Wales accounting for 12% of total capacity. [4]

Technology

The smelter currently comprises three potlines of 280 Pechiney AP18 (AP22) reduction cells each. [5]

Zinc smelting is the process of converting zinc concentrates into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.
