Sulphuric Acid - NEWS - 2002 Inco begins work on $115 million project to further reduce
SO2 emissions by 34 per cent in Sudbury SUDBURY, December 3, 2002 – Inco’s latest investment in
Sudbury The project will lower emissions from the current limit of 265

Florida-based Farmland Hydro is a limited partnership owned equally between Hydro Agri North America, Inc. and Farmland Industries, Inc. On May 31, 2002, Farmland Industries filed a Chapter 11 bankruptcy petition with the U.S. Bankruptcy Court in Kansas City. With the agreement, Cargill assumes complete operations of Farmland Hydro’s Green Bay fertilizer plant near Bartow, Fla. Cargill anticipates that it will retain approximately 270 of the 290 employees at the facility. As part of the agreement, Cargill also acquires approximately 15,000 acres of Farmland Hydro land currently being permitted for a phosphate mine operation. In connection with the sale, Cargill Fertilizer and Hydro Agri have entered into a strategic supply arrangement for the supply of ammonia by Hydro Agri, and MAP (mono-ammonium phosphate) and DAP (di-ammonium phosphate) by Cargill Fertilizer. Terms of the sale are not being disclosed. DA Calls for Independent Inquiry into Foskor Gas Leak CAPE TOWN July 17, 2002 - Reports from the province shortly after the
incident described the casualty departments of the town's hospitals as "war
zones", with medical staff battling to cope with dozens of nauseous victims, many of
whom had difficulty breathing. In a statement on Tuesday, Foskor expressed
regret over what it termed "an unfortunate incident". DA MPL Margaret Ambler-Moore on Wednesday said
her party welcomed news that Foskor was carrying out an internal investigation into the
disaster. "However, (we) also urge the Department of Environmental Affairs to
carry out their own independent investigation into the circumstances surrounding the
incident." The department on Tuesday issued a statement
saying it had called on Foskor for "a report detailing the reasons behind a sulphuric
acid leak". It is understood this report will be compiled by Foskor management,
and not by independent inspectors. It is also not clear whether it will be followed by an
inquiry into the accident. Ambler-Moore said it was "frightening
that... people have become victims of short-sighted planning on the part of Foskor, but
even more disturbing is the fact that this scenario had already been identified as a
possible worst-case scenario". She called on the department to establish: - what regular checks were being done at
industrial facilities in Richard's Bay; - what the existing pollution levels were in
the area; and, - what steps were being taken to prevent
recurrences of such incidents. A Pietermaritzburg-based NGO on Tuesday warned
that exposure to certain sulphur gases could prove "dangerous to life" and one,
sulphur trioxide, was potentially carcinogenic. Simon-Carves to offer Noram-Cecebe Technology 2002 - Noram-Cecebe announce that Simon-Carves Ltd. will be their
exclusive worldwide technology licensee apart from the Americas and Australia.
Simon-Carves were recently a licensee of Enviro-Chem Systems (Monsanto) technology but
terminated their agreement prior to partnering with Noram-Cecebe. DuPont
Chemical Solutions Enterprise to Provide Sulfuric Acid Services to Motiva Delaware City
Refinery DELAWARE CITY, Del., April 26, 2002 – DuPont Chemical Solutions
Enterprise and Motiva Enterprises LLC today announced a business agreement in which DuPont
would provide the Delaware City Refinery with sulfuric acid regeneration services.
Financial terms of the agreement were not disclosed. As part of the agreement, DuPont -- which has nearly 70 years of
experience in manufacturing and transporting sulfur-based products -- would supply the
Delaware City Refinery with sulfuric acid regeneration services by constructing a
state-of-the-art replacement facility on the refinery’s property. The unit will
create approximately 25 new DuPont jobs to operate and maintain the facility.
Construction of the unit will be undertaken by DuPont after appropriate permits are
obtained and will provide additional economic benefits to the Delaware area construction
industry. Motiva determined it would be advantageous for DuPont to construct and
operate a replacement facility at the refinery. This would allow Motiva to focus on
its core business of refining crude oil into finished products -- such as gasoline,
diesel, and home heating oil -- and maintain its competitiveness in the refinery industry. Sulfuric acid is used by the oil refining industry as a catalyst in the
alkylation process to make high octane gasoline. DuPont will recycle
“spent,” or used acid, and regenerate it for Motiva’s use again in the
refining process. DuPont services to Motiva will be a combination of supplying
sulfuric acid and taking back the “spent” acid to recycle at the DuPont-operated
facility for Motiva’s future use. Noranda's Gaspe Smelter to Close Permanently March 28, 2002 Blaze strikes WMC's Kalgoorlie nickel smelter February 21, 2002 - Another WMC operation has been damaged by fire. This time it was the group's nickel smelting operations at Kalgoorlie. The fire broke out in the sulphuric acid plant yesterday morning as it was being prepared for routine maintenance work. No injuries were reported and the nickel smelter was not affected. WMC said the cause of the fire and the extent of the damage were as yet unknown. Although the nickel smelter was not affected, its production levels in the near term could be affected by wind movements in the Kalgoorlie region. That is because of air-quality considerations. Without the acid plant, sulphur would be pumped up the smokestack for wind dispersal, assuming the wind is blowing away from the town. If the wind was not favourable, the smelter would be taken off line, as it used to be before the acid plant was built to meet tighter air-quality requirements. WMC noted that planned production from the nickel smelter for 2002, before yesterday's fire, was below its capacity of more than 100,000 tonnes. As a result, it expects to be able to recover "any short-term lost production over the duration of the year". Last year, WMC's Olympic Dam copper/uranium mine in South Australia was hit by a fire in its solvent extraction plant. The loss in production there has forced a writedown of $45 million after tax, which will show up in the group's 2001 profit report, due to be released next Tuesday. The profit is expected to reflect the impact of sharply lower metal prices, with a result of about $395 million tipped by analysts after knocking out a long list of one-off items, including the Olympic Dam hit. Cominco Reduces Zinc Production February 14, 2002 He said that zinc demand fell by 4% in 2001 and this has led to
rising inventories. While consumption is forecast to grow again in 2002, it will take
cutbacks such as these in order to bring supply and demand into balance. On the concentrate side, the Red Dog mine is now scheduling
shipments of 1,000,000 tonnes of concentrate in 2002, down from 1,060,000 originally
planned, or a reduction of 33,000 tonnes of contained zinc. Teck Cominco will work with its customers to minimize any
disruption to their operations and Cajamarquilla will ensure that its Latin American and
Japanese customers are supplied with the zinc they require. Employees at Trail have been asked to use vacation time during
the August shutdown period. Cajamarquilla will begin discussions with its employees, the
unions and the relevant government departments to ensure that all employees receive fair
and appropriate wages and benefits during the shutdown period. Outokumpu Planning Summer Shut-Down at
