    Originally built in 1933 by Japanese during their occupation, [1] the building used to be a copper and gold smelter plant called the Shuinandong Smelter that used to process refined ore from Jinguashi and Jiufen. [2] After the handover of Taiwan from Japan to the Republic of China in 1945, the refinery was taken over by the state-run company ...

    en.wikipedia.org/wiki/Aluminium_smelting

    A typical smelter contains anywhere from 300 to 720 pots, each of which produces about a ton of aluminium a day, though the largest proposed smelters are up to five times that capacity. Smelting is run as a batch process, with the aluminium deposited at the bottom of the pots and periodically siphoned off.

    Bloomery type furnaces typically produced a range of iron products from very low-carbon iron to steel containing around 0.21.5% carbon. The master smith had to select pieces of low-carbon iron, carburize them, and pattern-weld them together to make steel sheets. Even when applied to a noncarburized bloom, this pound, fold, and weld process ...

    The report estimates that chemical CO 2 absorption would cost $35/t of CO 2, plus $8–20/t CO 2 for transportation and storage. [95] At the time, this would have increased steel production costs by 15–20%, [ 88 ] [ citation needed ] presenting a barrier to decarbonisation for steelmakers which typically operate with margins of 8–10%. [ 96 ]

    To remove these impurities, the blister copper was repeatedly melted and solidified, undergoing a cycle of oxidation and reduction. [7] In one of the previous melting stages, lead was added. Gold and silver preferentially dissolved in this, thus providing a means of recovering these precious metals.

    A fire on 3 Sept. 1973, damaged 2 of the 7 sections in the smelter baghouse. The baghouse was not back in normal operation until 17 March 1974. The company actually increased lead production during this period, taking advantage of increased prices. Lead emissions increased to 35.3 tons per month, compared to 8.3 tons per month from 1955 to 1964.
