Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. It is a form of extractive metallurgy that is used to obtain many metals such as iron, copper, silver, tin, lead and zinc. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal behind. The reducing agent is commonly a fossil-fuel source of carbon, such as carbon monoxide from incomplete combustion of coke—or, in earlier times, of charcoal. The oxygen in the ore binds to carbon at high temperatures, as the chemical potential energy of the bonds in carbon dioxide is lower than that of the bonds in the ore.
ASARCO is a mining, smelting, and refining company based in Tucson, Arizona, which mines and processes primarily copper. The company has been a subsidiary of Grupo México since 1999.
Waterfall is a small suburb in southern Sydney, in the state of New South Wales, Australia. It is 40 kilometres south of the Sydney central business district in the Sutherland Shire. It is the southernmost suburb of Sydney in the eastern corridor, on the Princes Highway, bordering Helensburgh.
Lake Illawarra is an open and trained intermediate wave dominated barrier estuary or large coastal lagoon, is located in the Illawarra region of New South Wales, situated about 100 kilometres (62 mi) south of Sydney, Australia.
Dapto is a suburb of Wollongong in the Illawarra region of New South Wales, Australia, located on the western side of Lake Illawarra and covering 7.15 square kilometres (2.76 sq mi). As at the 2021 census, the suburb had a population of 10,954.
Port Kembla is a suburb of Wollongong 10 km south of the CBD and part of the Illawarra region of New South Wales. The suburb comprises a seaport, industrial complex, a small harbour foreshore nature reserve, and a small commercial sector. It is situated on the tip of Red Point: its first European sighting was by Captain James Cook in 1770. The name "Kembla" is an Aboriginal word meaning "plenty [of] wild fowl".
Dapto railway station is located on the South Coast railway line in the Wollongong suburb of Dapto, New South Wales, Australia.
Risdon is a suburb of Hobart, capital city of Tasmania. It is west of Risdon Vale.
Kanahooka High School is a government-funded co-educational comprehensive secondary day school, located in Kanahooka, 15 kilometres (9 mi) southwest of the city of Wollongong, in the Illawarra region of New South Wales, Australia.
Mount Isa Mines Limited ("MIM") operates the Mount Isa copper, lead, zinc and silver mines near Mount Isa, Queensland, Australia as part of the Glencore group of companies. For a brief period in 1980, MIM was Australia's largest company. It has pioneered several significant mining industry innovations, including the Isa Process copper refining technology, the Isasmelt smelting technology, and the IsaMill fine grinding technology, and it also commercialized the Jameson Cell column flotation technology.
William Beach was a professional Australian sculler. He was unbeaten as World Sculling Champion from 1884 to 1887.
Zinc smelting is the process of converting zinc concentrates into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.
Trail is a city in the West Kootenay region of the Interior of British Columbia, Canada. It was named after the Dewdney Trail, which passed through the area. The town was first called Trail Creek or Trail Creek Landing, and the name was shortened to Trail in 1897.
The Chillagoe smelters is a heritage-listed refinery at Chillagoe-Mungana Caves National Park, Mareeba Mining District, Chillagoe, Shire of Mareeba, Queensland, Australia. It operated in the early 1900s. It is also known as Chillagoe State Smelters. It was added to the Queensland Heritage Register on 21 October 1992.
Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the elemental metal. A reducing environment pulls the final oxygen atoms from the raw metal.
Electrona is a rural residential locality in the local government area (LGA) of Kingborough in the Hobart LGA region of Tasmania. The locality is about 12 kilometres (7.5 mi) south of the town of Kingston. The 2016 census recorded a population of 364 for the state suburb of Electrona. Electrona is also part of the Greater Hobart statistical area. It is a small residential area on the d'Entrecasteaux Channel in Southern Tasmania. It grew up around the Electrona Carbide Works which were established in 1909.
The ISASMELT process is an energy-efficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines and the Government of Australia's CSIRO. It has relatively low capital and operating costs for a smelting process.
The Bottom-blown Oxygen Converter or BBOC is a smelting furnace developed by the staff at Britannia Refined Metals Limited (“BRM”), a British subsidiary of MIM Holdings Limited. The furnace is currently marketed by Glencore Technology. It is a sealed, flat-bottomed furnace mounted on a tilting frame that is used in the recovery of precious metals. A key feature is the use of a shrouded lance to inject oxygen through the bottom of the furnace, directly into the precious metals contained in the furnace, to oxidize base metals or other impurities as part of their removal as slag.
Risdon Zinc Works is a major zinc refinery located in Lutana, a suburb of Hobart, Tasmania, Australia. The smelter is one of the world's largest in terms of production volume, producing over 280,000 tonnes annually of high-grade zinc, primarily as die-cast alloys and continuous galvanising-grade alloys. These products are exported for global markets and utilised in a wide range of industries and products, from building and infrastructure to transportation, business equipment, communications, electronics, and consumer goods. The facility produces zinc using the Roast, Leach, Electrowinning (RLE) method, creating leach byproducts, including cadmium, gypsum, copper sulphate, lead sulphate, sulphuric acid, paragoethite and leach concentrate. The refinery has been owned and operated by the global multi-metals business Nyrstar since 2007. Nyrstar Hobart works closely with the Nyrstar Port Pirie multi-metals smelter in South Australia. The facility is Tasmania's largest exporter, contributing 25% of the state's overall export value in 2013.
