Gas cleaning system with a Boliden mercury removal system is common to all
acid plants. Acid plant tailgas is treated in an ammonia scrubber. Liquid
SO2 is produced by acidulation of the scrubber bleed.

| General |
In smelting and refining, Teck Cominco Metals
owns and operates the integrated smelting and refining complex at Trail,
British Columbia. The complex’s major products are refined zinc and lead. It
also produces silver, gold, germanium dioxide, indium, cadmium and copper
compounds as metal co-products, along with a variety of sulphur products and
ammonium sulphate fertilizers.
Cominco started in 1906 as The Consolidated Mining and Smelting Company of
Canada, formed by the amalgamation of several units controlled by the
Canadian Pacific Railway. The company changed its name to Cominco in 1966.
Cominco's core Sullivan mine, which began production in 1909, would operate
for more than 90 years until its ore reserves were exhausted in 2001. |

March 16, 2010 - The Insurance Corporation of B.C. will destroy 18
vehicles belonging to employees of Teck Resources at the company's
operations in Trail, B.C., after damage resulted from a sulphuric acid spill
in January. The acid spilled from a line that runs between the Trail and
Warfield plants on Jan. 8 and emptied into a staff parking lot. ``We
couldn't predict the long-term effects so we can't guarantee safety,'' said
ICBC spokeswoman Michelle Hargrave. The leak affected 22 vehicles, each of
which received new tires from Teck Resources. But ICBC has determined that's
not enough for 18 of the vehicles. “Customers were advised the vehicles
would be crushed so that no affected parts from the vehicles could later
enter the used parts market or end up in a repaired or rebuilt vehicle,”
Hargrave said in an email. The 18 clients are being compensated by ICBC,
which is seeking to recover its costs from Teck Resources. Hargrave could
not say how much money is being awarded or the compensation amount ICBC is
seeking, but said the corporation is in negotiations with the company. The
Teck employees' insurance premiums will not be affected. A car that had the
least contact with the acid is being returned to an employee who owned it
because the vehicle was determined to be safe to operate. The three
additional damaged vehicles did not have comprehensive coverage with ICBC
and their owners are not being compensated by the public insurer.
Comprehensive coverage is optional and open to private competition in B.C.
Teck public affairs manager Richard Deane said he can't speak about
individual employees' insurance arrangements but the company is continuing
to work with those who've been affected by the spill. October 19, 2009 - A contract employee was burnt with acid from a sulfuric acid drain line during a routine shutdown of the roaster acid area of Teck’s Trail operation on Oct. 19. The contractor was treated for burns and released the same day at the Kootenay Boundary Regional Hospital (KBRH). “We were in the midst of a planned shutdown of this area that began Oct. 17 and will run until Oct. 29,” said Carol Vanelli-Worosz, public relations for Teck’s Trail operation. “We know he was discharged from the KBRH on the same day, but because he wasn’t our employee I have no further detailed information.” Vanelli-Worosz said the shutdown isn’t anything out of the ordinary for Teck and about 120 contract employees would be coming and going on site during the maintenance. She says an investigation is underway involving Teck, Work safe B.C. and Trail’s Local 480 United Steel-Workers Union. “We are committed to everyone leaving our worksite safely everyday and we take these incidents very seriously,” said Vanelli-Worosz. “There is now an investigation into the route causes of the incident to ensure it does not happen again.” July 30, 2009 - Teck Resources Ltd. said it will resume full production at its Trail, B.C., zinc smelter due to recovering demand for the metal. The company, Canada's largest base metals miner and a top producer of coal used in the steelmaking process, also said it has reached agreement with most of its coal customers on 2009 deliveries at $128 (U.S.) a tonne. This brings its average realized coal price for the 2009 calendar year to between $155 and $160 a tonne, when factoring in coal sold early in the year at higher 2008 prices. Teck slashed output at Trail by 20 per cent last fall as a result of plunging demand. It said it will raise output to 25,000 tonnes a month effective Sept. 1. The smelter had been operating at a rate of 20,000 tonnes a month. Mined zinc production will not be affected. Teck said a strengthening in customer demand over the past several months has depleted refined metal inventories. October 1, 2008 - Teck Cominco Limited (Teck) is pleased to announce the launch of its simplified name and brand, Teck, and the formation of five new strategic business units specializing in copper, metallurgical coal, zinc, gold and energy. “Seven years ago when Teck Cominco was formed, two strong Canadian companies with a tradition of excellence in mining and metal refining were brought together. Since then, we’ve grown stronger through the acquisition and development of a diversified range of commodities,” said Don Lindsay, President and CEO. “Today, under one simplified name and a new strategic business unit structure, Teck is well positioned to build on our strength as a diversified resource leader.” The new structure is designed to improve the company’s competitiveness by increasing Teck’s ability to analyze and act on available opportunities in each commodity segment. Each business unit is led by a senior executive with full responsibility for the unit’s performance including establishing a growth strategy, project identification and development, the safe and sustainable operation of the unit’s assets, delivering quality products to customers, and overall profit and loss accountability. April 30, 2001 -
The Boards of Directors of Teck Corporation and Cominco Ltd. are pleased to
announce today that the two companies have entered into a merger agreement.
The ongoing company will be named Teck Cominco Limited, preserving the two
most historic names in Canadian mining, with over 180 years of operating
history between them. Under the
merger agreement, implementation of which is subject to regulatory, court
and Cominco shareholder approvals and other customary conditions, Cominco
shareholders will receive 1.8 Class B subordinate voting shares of Teck plus
$6 in cash for each Cominco common share held. This represents a premium to
Cominco shareholders of 21% over the average closing prices of the two
companies in the 20 trading days prior to this announcement.
Dr. Norman B. Keevil, Chairman and CEO of Teck and Chairman of Cominco,
stated: "The merger will result in a substantial, diversified, mining
company with a larger market capitalization and much greater liquidity than
either of the predecessors. The new Teck Cominco will have strong cash flow
from world-class assets. The combined company's exceptional pipeline of
expansion and development projects will fuel its ongoing growth. Chief among
these projects are: the current expansion of capacity at the Red Dog zinc
mine; the nearly-completed Antamina copper, zinc mine; the planned
expansions of the Cajamarquilla zinc refinery and the Elkview coal mine; and
the Pogo gold and San Nicolas copper, zinc projects currently at the
feasibility study stage." Dr.
Keevil pointed to the trend towards consolidation in the mining industry to
create stronger, more competitive companies, with the recently announced
merger of BHP and Billiton being just the latest example.
He said: "With consolidation occurring across country borders around the
world, it is only logical that two related companies based in the same city,
with a number of joint operations and a significant proportion of common
shareholders, join forces to become more competitive in the world mining
industry." |
