General | The
Auby smelter is located in the town of Auby in the north of France,
approximately 35 kilometres south of the city of Lille. The plant is
situated on a site of 138 hectares. It is adjacent to the canal de la Deûle,
which connects to the seaport of Calais, and is well connected to several
motorways. Zinc smelting at the site dates back to 1869. The majority of
site production is sold to the Umicore building product plant located
adjacent to the aite, as well as to Nyrstar Balen/Overpelt for conversion
into alloys. In addition to producing standard zinc cathodes, the plant
also produces a significant quantity of higher quality battery-grade
cathodes The site's by-products include sulphuric acid, Auby leach product,
copper and an indium concentrate. History Auby Plant was established in 1869 by Compagnie Royale asturienne des Mines, in the middle of Coal mines area in order to access energy required for the industrial thermical process of refi ning zinc. This process remained almost unchanged until 1954, when Auby Plant modernized its process Introducing a vertical furnace “ New Jersey “. Later in 1975, the refi ning technology moved from thermical one to an hydrometallurgic (electrolysis), which is still the current process today. This major technological advancement enabled the Plant to reach 100,000 tonnes annual zinc production capacity, until the 1987 integration into “Vielle Montagne Group as “Union Miniere” and subsequently “Umicore” in 2001 increased capacity to 200,000 tonnes zinc per year. Due to downsizing capacity in 2005 to 135,000 tonnes, available infrastructure on site paved the way for the establishment of Indium Cement in 2007, coinciding with the plant’s integration into Nyrstar Group. Between 2009 and today, the plant has increased zinc production capacity to 160,000 then to 172,000 tons and developed and Indium metal refi ning process. This resulted in the 2012 establishment of an Indium Metal Production facility with an annual capacity of 48 tonnes |

December 17, 2021 - The decision comes in
response to a significant rise in power prices in France.
Belgium-based global metals firm Nyrstar plans to place its operations in
Auby, France, on care and maintenance from the first week of January 2022,
due to increasing power prices. The decision comes in response to
significantly increased current and anticipated future prices of electricity
in the country. In a press statement, Nyrstar said: “Power prices,
already at historically high levels across Europe, have continued to rise in
recent weeks in France, in excess of neighbouring European countries.
“This is as a result of low availability of nuclear power, high
carbon-related costs passed on by power companies and reduced fixed-price
allowances for the industry.” Nyrstar said that electricity prices in
early 2022 in France could stay high and volatile. During the care and
maintenance period, the firm plans to undertake maintenance and continue
planned investment into the project. Furthermore, employees at the
Auby operations would be redirected to work on training maintenance and
investment projects. The firm plans to resume production at Auby once
it is economically viable. In Auby, Nyrstar operates a mid-scale
electrolytic zinc smelter, which produces cathodes as finished products. It
uses both zinc concentrates and zinc secondaries as feedstock. The
smelter is designed to process a high percentage of secondary feed material
to produce SHG cathode and some extra pure quality cathodes. The site
also produces by-products of sulphuric acid, Auby Leach Product, copper and
indium. Nystar will continue to run its three European operations in
France, Belgium and the Netherlands, though with a production reduction of
up to 50% due to high power prices. |
