The Tasmanian Electro Metallurgical Company (TEMCO) is Australia's only manganese alloy smelter and supplies two types of this critical steel additive to more than fifty companies around the globe. BHP Pty Ltd built the TEMCO plant in the early 1960s, at Bell Bay, near George Town. When the plant was opened on 11 May 1962, TEMCO formed a major part of the state's industrial sector – and remains so today. TEMCO's employment figures peaked at 475 in the early 1980s. The company's four electric-arc furnaces produce more than 250,000 tonnes of manganese alloys annually, eighty percent of which is exported. BHP sold the plant to Billiton PLC subsidiary, Samancor Pty Ltd, in 1998, but re-established its association with TEMCO a few years later in a merger which created BHP Billiton Pty Ltd.
