(MERAF) for the Base Metals Smelting Sector - CCME

• Ammonia Utilities (Ammonia I Plant, Utilities I Plant, and effluent
management system); and
• Chemical Utilities (Urea I Plant, Phosphate Plant, Sulphuric Acid Plant,
and Fertilizer Loadout).
The original refinery in Fort Saskatchewan, Alberta was commissioned. In 1955.
It consisted of the Leach, Copper Boil, Metals Recovery, Sulphide Precipitation,
and Ammonium Sulphate circuits. In 1992, the refinery was expanded and the
Cobalt Separation, Cobalt Recovery, and Ammonia Recovery Circuits were
constructed. In 1996, a further expansion was undertaken to increase the
capacity.
The Metals Refinery produces two products, three by-products, and one waste.
The products are pure nickel and pure cobalt. The by-products include
ammonium sulphate, copper sulphides, and zinc sulphides. The waste includes
solid tailings from the refining process.
2.6.3. Hudson Bay Mining & Smelting Co. Ltd
Hudson Bay Mining & Smelting 38,39 operations are centered at Flin Flon in the
province of Manitoba, Canada. It owns and operates several underground mines
in Manitoba and Saskatchewan which produces zinc, copper and gold ores. Gold
is produced as a by-product from refining of the copper anodes. A new shaft is
currently being sunk to exploit the recently discovered 777 deposit in Flin Flon. A
modern zinc electro-winning tank house is also under construction.
The Flin Flon ore body was discovered by David Collins, a local trapper, and
shown to Tom Creighton, a prospector, in 1914. It took more than a dozen years
to bring the mine into production. In 1927, the Whitney family of New York
created HBM&S which took over controlling interest in the Flin Flon property. By
1930, the mine, smelter, a hydroelectric dam and a railroad were all in full
operation.
Today, Hudson Bay Mining and Smelting is wholly-owned by Anglo American plc,
a natural resources company incorporated in England and Wales
Hudson Bay Mining & Smelting Co. Ltd. (HBM&S) operates a mill, copper smelter,
and zinc plant at their metallurgical complex in Flin Flon, Manitoba. Copper and
zinc ores from surrounding mines have been processed at the facility since 1930.
The zinc refinery originally used a roast-leach-electrowinning process, but in 1993
was converted to the world's first commercial application of the Sherritt two-stage
pressure leach process. Refined zinc is recovered by electrowinning.
