- New smelter was commissioned as well as the first double absorption plant. 1989 - Mercury Removal system installed The NA Group is the largest copper producer in Europe and as well the largest copper recycler worldwide. It produces about 800,000 tonnes of copper and copper products annually and with about 3,200 employees is one of the leading copper producers worldwide. The core business is the production of copper cathodes from copper concentrates, copper scrap and recycling materials. These are then processed into continuous cast wire rod and shapes, rolled products and copper alloys. Precious metals are likewise an important product sector. Further specialty products produced and marketed by the NA Group are all the major natural by-elements from copper production. These are processed, for example, into sulphuric acid and iron silicate stone. |

- Germany's Aurubis today announced that its Hamburg copper smelter returned
to service on 11 July from the largest maintenance shutdown in the company's
history that began 7 May.
A restart is now under way following the €95mn 60-day maintenance
that included an overhaul of the flash smelter, installation of heat
exchangers in the contact acid plant, as well as the installation of a tap
hold drill and tamping machine for improved safety of copper slag tapping.
Hydrogen-ready anode furnaces were also installed as measures to improve
sustainability.Investments in automation are set to improve efficiency and
extend the frequency of planned maintenance rounds to three years from
two.The Hamburg smelter's outage has exacerbated sulphuric acid tightness in
Europe, and the operational restart is expected to provide some relief to
the market. This comes in addition to the lack of availability of molten
sulphur in the region, leading to shortages of sulphur burnt acid, which has
prompted some consumers to replace burnt acid with smelter acid, lifting
demand.Aurubis produced 1.19mn t of sulphuric acid during the first six
months of the 2023-24 financial year (October-March), up by 1pc on the same
period a year earlier. Output at Aurubis' Hamburg smelter rose by 11pc to
512,000t in the period, while output from the Pirdop smelter saw a 6pc
decline on the period to 679,000t.For the first three months of the year,
Aurubis produced 598,000t of acid, unchanged from the same quarter of
2022-23, as increased output at its Hamburg smelter offset a decline from
Bulgaria's Pirdop plant. Production at Hamburg totalled 258,000t from
January-March. June 28, 2022 - The planned maintenance shutdown at the Hamburg Aurubis plant was successfully completed today. Aurubis carried out a total of 480 technical renovations and maintenance measures throughout the smelter, as well as taking action to improve the site’s environmental protection. In addition to inspecting the waste heat boiler, the multimetal company renovated the plant’s highest forge, which stretches up to 135 meters, installed two new metallurgical cranes and replaced heat exchangers in the contact plant – the latter of which was done in preparation for the second expansion stage of industrial heat extraction project to supply up to 20,000 households in Hamburg with CO2-free industrial heat as early as 2024. With this shutdown, we have invested a total of € 72 million in the increased effectiveness of our production facilities and the further improvement of the site’s environmental protection – € 59 million in just this year, explains Aurubis Chief Operating Officer (COO) Heiko Arnold. The shutdown lasted a total of 56 days, 11 days longer than originally planned. Unfavorable weather conditions, which delayed certain crane operations due to high winds, and necessary additional work that could only be identified after operations were shut down, led to the longer maintenance time. “When it comes to the quality and safety of our maintenance work and production facilities, we don’t make any compromises. We put great value on the flawless execution of all this work, so we took more time to complete it in order to now be able to safely and reliably return to production,” emphasizes Heiko Arnold.
December 16, 2013 - German copper smelter Aurubis expects
profits to bounce back this fiscal year from a sharp fall in the previous
one, thanks to strong demand from China and a rise in the price for
treatment and refining paid by miners.
Europe's largest copper producer said on Monday its operating
earnings fell 62 percent to 114 million euros ($157 million) in the year
ended Sept. 30, with turnover down 10 percent to 12.34 billion euros.
It had said on Nov. 5 that earnings before taxes would drop by more
than half due to weak copper scrap and acid markets, low metal yields, a
scheduled maintenance shutdown at its main refinery in Hamburg, and
modernisation in rolled product works.
"Although the first quarter will be strained by the large-scale
shutdown in Hamburg and the restructuring of Business Line Flat Rolled
Products, we are confident that we will return to a much better earnings
level in fiscal year 2013/14," Chief Executive Peter Willbrandt said on
Monday. The company does not
expect a loss in the first quarter of the new financial year, Willbrandt
added at a press conference to present the company's results.
Aurubis proposed a dividend for 2012/13 of 1.10 euros per share, down
from 1.35 euros the previous year.
"The global copper market will likely be characterised by good demand
for cathodes (new metal) for much of 2014," the company said, pointing to
continued strong demand from China.
"The copper price is well supported from the current perspective.
Many developments show that it has upward potential, though the trend will
be volatile overall." Copper
prices touched a six-week peak on Friday in a sixth straight session of
gains as nervous investors bought back short positions before a U.S. central
bank meeting.
February 14, 2012 - Aurubis AG,
Europe's largest copper producer, warned on Tuesday that a 40 percent rise
in net profit for the first quarter was unlikely to be repeated over the
rest of the year because of an uncertain economic outlook.
"We view the copper market as well supported despite economic
uncertainties and expect volatile yet high ongoing copper prices," it said.
"On the sales markets, especially for sulphuric acid and copper
products, we are confronted with the effects of subdued economic
expectations and doubts regarding the further development of the financial
crisis." It added: "We do not
expect the results of the very good first quarter to continue to this
extent. Nevertheless, we anticipate a satisfactory annual result overall on
the basis of this good quarterly result."
Aurubis said on Friday its operating earnings before taxes in the
first quarter of its new financial year rose to 86 million euros, up from a
loss of 21 million euros in the same quarter last year.
Aurubis earnings before taxes (ebt) were 190 million euros in the
quarter ending Dec. 31, up from 135 million in the previous year. Net profit
rose 40 percent to 136 million.
Quarterly revenue rose to 3.151 billion euros from 2.732 billion in the
previous period despite a lower average copper price of $7,489 a tonne
against $8,634 in the prior year.
The increase was largely due to the integration of the purchase of
the rolled copper products division from copper group Luvata. Higher
precious metal prices overcompensated for the declining copper prices,
Aurubis said. The first quarter
saw a combination of positive factors in its major business areas, it said.
Copper concentrate (ore) throughput was well above the throughput
level of the first quarter of the prior year, which was lower due to
temporary plant shutdowns. Higher copper treatment and refining charges
(TC/RCs), the fees paid by copper mines and others to refine concentrate
into metals, were collected at the same time.
Higher sulphuric acid prices with higher sales volumes compared with
the prior-year quarter had a "distinctly positive" effect on consolidated
earnings. Higher refining
charges in copper scrap processing and increasing input quantities of
recycling materials led to positive contributions to earnings.
Aurubis on Jan. 19 posted an 84 percent rise in full year 2010/11
earnings meeting analysis' forecasts following a good performance in its
main business sectors plus a change in inventory valuations.
