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.
[1] In a blast furnace, fuel ( coke ), ores , and flux ( limestone ) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres , so that the chemical reactions take place throughout the furnace as ...
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]
It cost $16.3 million at the time to build, [1] [7] equivalent to $101 million in 2023. The top can be accessed by a Swedish-built elevator that crawls up a gear track on the inside surface. It takes 20 minutes to ascend the stack, although workers only need to travel up to the 300-foot level each day, to service the air-sampling station. [1]
This is a list of primary aluminium smelters in the world. Primary production is the process by which alumina is smelted to pure aluminum. [1] Secondary production is the process of recycling aluminum scrap into aluminum that can be used again. [2]
Behind the smelter and the engine sites is a stone retaining wall up to 1.8 metres (5 ft 11 in) high. Above this wall is a flat area that appears to have been an ore sorting or treatment floor. To the east of the smelter area is a 28-metre (92 ft) long tip of mullock, and to the east of that again is a large area of mullock and ore dump that ...
