Unfortunately, we will not be able to see the Slag Pouring
Formerly a popular attraction in Sudbury, slag pouring has disappeared from the public eye and is no longer considered an attraction in Sudbury.
Every few hours, molten ore smelting waste (called slag) was moved by train to the huge piles in the northwest part of the city. The liquid slag
was dumped from the top of the piles, resulting in a spectacular volcano-like spectacle.
It is now impossible to view a slag dump from a public spot due to a green reclamation of the slag hill.
See: http://en.wikipedia.org/wiki/Inco_Superstack
The Inco Superstack in Sudbury, Ontario, with a height of 380 meters (1,250 ft), is the tallest chimney in Canada and the Western hemisphere,
and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest
freestanding structure of any type in Canada, ranking behind the CN Tower .
The structure was built to disperse sulphur gases and other byproducts of the smelting process away from the city itself.
As a result, these gases can be detected in the atmosphere around Greater Sudbury in a 240 kilometers (150 mi) radius of the Inco plant.
Prior to the construction of the Superstack, the waste gases contributed to severe local ecological damage. Compounded by open coke beds
in the early to mid 20th century and logging for fuel, an inevitable near-total loss of native vegetation occurred.
If Vale considers further reductions in emissions with 21st century technologies,
the Superstack might no longer be needed, and could be converted into a communications observation tower.
SO2 reductions have reached the point where the natural draught from the heat of the SO2 is no longer sufficient.
Natural gas burners and fans are now needed to move the SO2 up the stack.
We will visit Ukrainian churches in Sudbury:
Holy Protection of the Mother of God - Sudbury
st michaels church - Coniston ontario
The Sudbury Neutrino Observatory (SNO) is a neutrino observatory located 6,800 feet (about 2 km) underground in Vale Inco's Creighton Mine in Sudbury,
Ontario, Canada. The detector was designed to detect solar neutrinos through their interactions with a large tank of heavy water. The detector turned on
in May 1999, and was turned off on 28 November 2006. While new data is no longer being taken the SNO collaboration will continue to analyze the data
