November 26, 2012 - Incitec Pivot yesterday took delivery of a vital part to fix its waste hear boiler, after the boiler’s failure two weeks ago forced the company’s acid plant to close. Delivering the equipment from Europe was one of the largest planes to ever land in Mount Isa, a 50 metre Russian Ilyushin I1-76 cargo plane, the North West Star reported. Pilot Andrew Erstropov said despite heavy cargo and the size of the plane, Mount Isa airport handled the situation well. “The condition of the runway was good and the weather was clear, there were no problems,” he said. Having the ability to handle such a large aircraft allows Rockhampton Airport to cater to all different industry requirements, councillor and chair of council’s business enterprise committee Neil Fisher said. “This is an aircraft that is capable of carrying five Apache helicopters,” he said. “If we can handle the Antonov, we can easily use our resources to cater to the needs of the mining community, enabling Central Queensland mines to have their equipment shipped in by air rather than by road.” Fisher said. The acid plant is still expected to be shut for one month an Incitec Pivot spokesperson said. This will lead to decreased ammonium nitrate production at Phosphate Hill and losses estimated at $25 million before tax, Manufacturers’ Monthly reported earlier this month. Australian Mining found that the extended closure of Incitec Pivot's acid plant in Queensland had resulted in Xstrata's copper smelter's increasing sulphur dioxide emission levels. The acid plant near Mount Isa previously took around 80 per cent of the Mount Isa Mines' smelter's byproducts and emissions to create sulphuric acid for fertilisers. While it is shut down emissions are all released via the stack. "During the shut down maintenance period of Incitec Pivot Limited, 100 per cent of our sulphur dioxide is sent through to our copper stack," an Xstrata spokesperson explained. She went on to stress that the increased emissions would not reach harmful levels. November 12, 2012 - Fertiliser maker Incitec Pivot Ltd says the shutdown of a Mt Isa sulphuric acid plant for up to a month could cost it $25 million. The waste heat boiler at the Queensland plant failed, and the plant may need to be offline for up to a month in order for repairs to be made, Incitec Pivot said. The closure of the Mt Isa plant will cause reduced operations at the ammonium phosphate plant at Phosphate Hill, south of Mt Isa. That could reduce the plant's production of ammonium phosphates in the year to September 30, 2013 to 900,000 tonnes, the company said. If the Mt Isa plant is offline for a month, the financial implication of higher costs of sulphuric acid and repairs is estimated to be in the region of $25 million, before tax, Incitec Pivot said.
Sulphur dioxide fumes from
Xstrata Copper's smelter in Mount Isa in north-west Queensland will be
captured and made into fertiliser again, after repairs to equipment at a
facility.
March 6, 2012 - The extended shut down of the Incitec
Pivot acid plant has resulted in increased sulphur dioxide emissions from
Xstrata's copper smelter. Since
2000, the acid plant has taken the bulk of the copper smelter's emissions to
create sulphuric acid used to make fertiliser, about 80 per cent.
An Xstrata Mount Isa Mines spokeswoman said all emissions were
currently being released through the stack.
"During the shut down maintenance period of Incitec Pivot Limited,
100 per cent of our sulphur dioxide is sent through to our copper stack,"
she said. She said the increased
emissions would not reach harmful levels.
"During the shutdown of the acid plant, Xstrata Mount Isa Mines will
continue to operate its smelters in accordance with procedures undertaken by
its air quality control system, which is the most intensive air quality
monitoring system of any city in Australia," she said.
"The air quality control system in Mount Isa directs the smelters to
shut down if unfavourable wind conditions blow smelter emissions eastwards
towards town and they impact the local community."
Incitec Pivot had to extend the routine maintanence shut down of its
acid plant when workers discovered extra work needed to be done.
The acid plant is expected to be back online by mid to late March.
Incitec Pivot has estimated the shutdown will reduce its annual
profit by $21 million.
February 23, 2012
- Incitec Pivot Limited (ASX: IPL) today announced that there will be a
one month extension to its planned maintenance turnaround at its Mount
Isa Sulphuric Acid plant. The extended turnaround will reduce
production of Sulphuric Acid from the Mount Isa plant, resulting in the
Ammonium Phosphate plant at Phosphate Hill operating at reduced rates
during this period. The impact of this is estimated to be a 40,000 tonne
reduction in the production of Ammonium Phosphates at the Phosphate Hill
plant, resulting in the expected production of Ammonium Phosphates at
that plant for the financial year ended 30 September 2012 to be 880,000
tonnes. The financial impact to net profit after tax is currently
estimated to be $21 million.
December 21, 2011 - Mount Isans should be
breathing cleaner air in the New Year now that Xstrata Mount Isa Mines has
been made to operate under tougher air and water emission regulations
yesterday. Xstrata MIM will now
have to comply with stringent environmental regulations, and is now bound by
the Environmental Protection Act.
Since 1985 the mining operations had been exempt from the Act and has
operated under its own special legislation.
Under the regulations set down by the Department of Environment and
Resource Management (DERM), Xstrata will be required to significantly cut
sulphur dioxide emissions and comply with more stringent standards for air
and water quality. DERM
environmental services regional manager Rob Lawrence said the transition was
part of a wider plan to ensure all Queensland mines operated under the same
legislation. "Mines that
previously operated under special agreement acts are now required to have
approvals under the Environmental Protection Act. This means the same rules
apply across every operation in the state."
Mr Lawrence said DERM was working with Xstrata to ensure the company
met its environmental obligations.
"We recognise that considerable work and investment is required to
bring the Mount Isa operation up to contemporary standards," he said.
"This will take time. However the Department of Environment and
Resource Management is working closely with MIM to ensure the transition to
the new standards occurs in a timely fashion while also ensuring the risk to
the environment is minimised."
Xstrata Copper North Queensland chief operating officer Steve de Kruijff
said Xstrata had spent $275 million on environmental initiatives since the
Swiss mining company acquired the operation in 2003.
"We are planning to invest a further $360 million over the next five
years to continue improving our performance," he said.
Xstrata plans to close its Mount Isa copper smelter, which emits the
sulphur dioxide, by the end of 2016.
Xstrata is due to submit a new environmental management plan to the Qld
Government by Friday on its Mount Isa operations.
Mining giant Xstrata says its decision to phase out copper smelting and
refining in Mt Isa and Townsville in north Queensland has not been motivated
by the Federal Government's carbon tax.
The company will shut down both operations by the end of 2016.
Xstrata has told its 420 staff in the Mount Isa and Townsville facilities it
will offer retraining and relocation to retain them.
Xstrata chief operating officer Steve de Kruijff says its Australian
operations cannot compete with China, but the carbon tax is not to blame.
"What we've found is that the emerging Chinese metal processing industry is
producing copper at a far more marginal rate then we can do that," Mr de
Kruijff said. "We don't believe that our smelting and refining processes can
be sustained into the future.
"We don't see a turnaround in the profitability of smelters from a global
perspective and/or refining."
Xstrata says it will focus on the expansion of existing mines and the
development of new mines at Mount Isa and the broader region.
Xstrata says the Ernest Henry Mine at Cloncurry will not be affected by the
decision. It is unclear what the announcement will mean in terms of job
losses but the company says it needs to evolve the business to secure its
long-term future. The
announcement comes at the same time Xstrata is preparing an environmental
management plan to submit to the State Government on its Mount Isa mine
operations. Xstrata is due to
submit a new environmental management plan to the State Government by Friday
on its Mount Isa operations.
Queensland Resources Council chief executive officer Michael Roche says
Xstrata's decision highlights the risk of introducing a carbon tax.
"This just shows you just how vulnerable [the industry] can be to additional
cost impost, which is why of course we're trying to fend off the worst of
the carbon tax at the moment," he said. Mr Roche says the move shows how tough the market is becoming
for Australian companies.
"Without our competitors also having some sort of carbon pricing mechanism,
it's just going to get harder and harder for us to compete," he said.
Mount Isa Mayor John Molony says he thinks uncertainty over the Federal
Government's carbon tax may have influenced Xstrata's decision.
"It's a dangerous time of the year for big mining companies like Xstrata
when you get the Federal Government announcing a carbon tax without
details," he said. "The mining
company will automatically budget for the worst-case scenario.
"It might please [Greens Senator] Bob Brown but it doesn't please the mining
operators." The Townsville Port
handles around 600,000 tonnes of copper product a year.
The port exported more than 500,000 tonnes of copper last financial year and
imported 100,000 tonnes from South America to be refined in Townsville.
Townsville Port chief executive Barry Holden says it is too early to know if
Xstrata's decision will have a major impact on the port because there is
scope to export more concentrate from the Ernest Henry mine.
"At this particular point in time we intend to wait and just see what the
advices are from Xstrata and some more detail in terms of any changes that
will occur in their tonnages through the port," he said.
"As always we will work with them to achieve the best outcome for them." February 9, 2011
October 13, 2010 - A mechanical problem at Incitec Pivot's Mount
Isa acid plant has resulted in more visible emissions from Xstrata's copper
smelter in recent days. The acid plant extracts metalliferous gases
from the copper smelter, including sulphur dioxide, however only two thirds
of the normal level of extracted gases were being removed due to a breakdown
in one of the plant's two blowers, an Incitec Pivot spokesperson said.
The acid plants produces sulphuric acid which is transported to Phosphate
Hill, south of Mount Isa, to produce fertiliser. The spokesperson said
the breakdown was not having any impact on fertiliser production because the
company could supplement acid from other sources. The
spokesperson said Xstrata were notified of the equipment failure when the
blower first stopped working. Xstrata's 2009 sustainability report
said sulphur dioxide emissions went up in the reporting year due to downtime
at the acid plant. The repairs to the damaged blower are
expected to be complete by mid next week.
March 5, 2010 - INCITEC Pivot's sulphuric acid plant has a new
operations manager. Brian
Corrie has moved to Mount Isa from Sydney to take on the new role.
Mr Corrie said he was excited about his new position.
"It was a good opportunity from a job point of view. I have the knowledge
and experience to do the job well," he said.
"The new job is very exciting. It's a challenge and an opportunity to grow
in a big company." But Mount
Isa is more than just a rung on the ladder for Mr Corrie, who said he had no
intention of leaving anytime soon.
"I'm settling into Mount Isa and I'm going to be here for the long term," he
said. Mr Corrie has a
background in metallurgy and spent 24 years in the platinum industry in
South Africa. He also worked
with Cement Australia in Gladstone, which he said helped him to prepare for
Mount Isa. The plant Mr Corrie
is in charge of employs about 50 people and uses metgas from the
neighbouring Xstrata copper smelter as the main feedstock to produce
sulphuric acid. The acid is
transported by rail to Incitec's plant at Phosphate Hill, where it is used
to manufacture fertiliser for Australia and export markets.
February 26, 2010 - The shutdown of copper operations at Xstrata
Mount Isa Mines and Incitec Pivot Limited's Phosphate Hill fertiliser and
Mount Isa sulphuric acid plants for maintenance will inject millions of
dollars into the community.
Final preparations are being made for the shutdowns which start next Tuesday
at the three operations. It should be completed by March 31.
For Incitec Pivot the shutdown will cost $56 million in goods and services
and will involve more than 900 fly-in contractors from more than 75
companies working across both sites.
About 250 of the contractors will work on projects at the acid plant and
live in Mount Isa for between two and three weeks. They will be housed at
four caravan parks. Another 625
extra personnel will be engaged at Phosphate Hill during the course of the
shutdown and will live on site.
For Xstrata the shutdown is the final stage of a $34million dollar project,
this stage will cost about $28million.
The company said the copper smelter had engaged several local and outside
contractors who were specialists in maintenance shutdowns. Collectively they
would provide about 330 contractors to work on the copper smelter re-brick.
The re-brick will involve replacing the refractory (brick) linings of the
vessels which convert concentrate to anode through a series of smelting
processes. The copper smelter
re-brick will use about 1000 tonnes of special thermal bricks which are
sourced from Europe. They are not made in Australia.
340 tonnes of bricks will be used in the Rotary Holding Furnace, 240 tonnes
of bricks in Anode Furnace 2 and about 420 tonnes of bricks in the Copper
ISASMELT Furnace. At Xstrata,
the shut down will affect mainly the copper smelter maintenance and
operational employees. Some engineering personnel will be involved in the
Xstrata project. The Incitec Pivot Limited (IPL) shutdown is planned as is
the Xstrata shutdown and will have no impact "on upstream or downstream
parts" of Xstrata's operations. |
