In 2017, PT Timah embarked on a transformational journey in the world of tin smelting, partnering with Metso to usher in a new era of efficiency, sustainability and technological advancement within their operations. To address the challenge of declining concentrate grades, a more intense smelting process with higher energy efficiency and reduced operating costs was required for their Muntok smelter. Enter: The Ausmelt® TSL Process for tin smelting.
PT Timah engaged Metso to provide engineering design, core proprietary equipment supply, training and commissioning services as well as spare parts for a new Ausmelt® Top Submerged Lance (TSL) Tin Smelter in West Bangka, Indonesia. A single Ausmelt® TSL furnace - capable of producing 45,000 tonnes of crude tin bullion annually – was to replace their six existing reverberatory furnaces.
The value of this transition is almost immeasurable. In addition to increasing profitability, its impact on the community continues to prove significantly positive.
“PT TIMAH TBK's new smelter will increase the added value of domestic tin processing, provide added value in the country, and create more jobs," says Joko Widodo, President of Indonesia.
