Horne Smelter
The Horne Smelter () is an industrial complex in Rouyn-Noranda, Quebec. It is Canada's only copper smelter, and the largest processor of metals from electronic scrap in North America. History The smelter is named after prospector Edmund Horne. The first copper pour took place on December 17, 1927. Operations The smelter produces copper anodes of 99.1% purity. Its feedstock consists of both copper concentrate sourced from mines and shredded electronic waste. Copper from electronic scrap comprises 15% of its production. In addition to copper and other metals, the facility also produces sulfuric acid. Commissioned in 1989, production from the sulfuric acid plant amounts to 640,000 metric tons per year, recovering some 96% of the sulfur generated by the smelting process. Economic impact The smelter employs around 650 people. Its economic benefit has been placed at $500 million per year. Environmental issues Emissions Emitting 100 nanograms of arsenic per cubic me ...

Rouyn-Noranda
Rouyn-Noranda (; Canada 2021 Census, 2021 population 42,313) is a city on Osisko Lake in the Abitibi-Témiscamingue region of Quebec, Canada. The city of Rouyn-Noranda is coextensive with a territory equivalent to a regional county municipality (TE) and Census geographic units of Canada, census division (CD) of Quebec of the same name. Their geographical code is 86. History The city of Rouyn (named for Jean-Baptiste Rouyn, a captain in the Régiment Royal Roussillon of Louis-Joseph de Montcalm) appeared after copper was discovered in 1917. Noranda (a contraction of "North Canada") was created later around the Noranda (mining company), Horne mine and foundry. Both were officially constituted as cities in 1926, then merged in 1986. Since 1966, Rouyn and Noranda constitute the capital of the Abitibi-Témiscamingue region. It is also the seat of (UQAT) since 1983. The population tends to increase or decrease dramatically depending on the economic situation. The city's populati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (English in the Commonwealth of Nations, Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula . It is a colorless, odorless, and Viscosity, viscous liquid that is Miscibility, miscible with water. Pure sulfuric acid does not occur naturally due to its Dehydration reaction, strong affinity to water vapor; it is Hygroscopy, hygroscopic and readily absorbs water vapor from the Atmosphere of Earth, air. Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Pollution
Air pollution is the presence of substances in the Atmosphere of Earth, air that are harmful to humans, other living beings or the environment. Pollutants can be Gas, gases like Ground-level ozone, ozone or nitrogen oxides or small particles like soot and dust. It affects both outdoor air and indoor air. Natural sources of air pollution include Wildfire, wildfires, Dust storm, dust storms, and Volcanic eruption, volcanic eruptions. Indoor air pollution is often Energy poverty and cooking, caused by the use of biomass (e.g. wood) for cooking and heating. Outdoor air pollution comes from some industrial processes, the burning of Fossil fuel, fossil fuels for electricity and transport, waste management and agriculture. Many of the contributors of local air pollution, especially the burning of fossil fuels, also cause greenhouse gas emissions that cause climate change, global warming. Air pollution causes around 7 or 8 million deaths each year. It is a significant risk factor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollution In Canada
Pollution is an Environmental issues in Canada, environmental issue in Canada. It has posed Health effect, health risks to the Canada, Canadian population and is an area of concern for Canadian lawmakers. Air, water and soil pollution as well as the associated health effects are prominent points of contention in modern Canadian society. Air pollution Air pollution in Canada is caused by industrial and vehicle emissions, agriculture, construction, wood burning, and energy production. Ongoing monitoring of Canada's Air Pollutant Emissions Inventory shows that 14 of the 17 of the air pollutants monitored are decreasing compared to historical levels. Data of 2019 shows that Canada is expected to meet or exceed its emission reduction commitments for 2020, as per the amended Gothenburg Protocol. Oil sands pollution While overall pollution levels have dropped, it was found that oil sands, oil sand pollution has increased by 20% since 2009. Tar sands facilities were found to be am ...
