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 ...
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining the final material is chemically identical to the raw material.
The Anaconda Smelter Stack is the tallest surviving masonry structure in the world, with an overall height of about 585 feet (178.3 m), including a brick chimney 555 feet (169.2 m) tall and the downhill side of a concrete foundation 30 feet (9.1 m) tall.
Bloomery type furnaces typically produced a range of iron products from very low-carbon iron to steel containing around 0.2–1.5% 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 ...
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.
Then in 1976, the company decided to build a 715-foot stack at the lead smelter, and a 610-foot stack at the zinc plant, to better disperse emissions. [3]: 179, 186, 188–190 In 1983, the Bunker Hill smelter was added to the National Priorities List as a Superfund site by the United States Environmental Protection Agency. [2]
March 15, 2023 - Production at the smelter will be reduced to approximately 75 percent of the site’s total consolidated capacity of 358,000 metric tons per year (mtpy). Alcoa’s share of the total capacity is 197,000 mtpy. The smelter, which has a total of 408 pots, had previously been operating at about 95 percent of its total capacity.
