| General |
La Caridad complex includes a
smelter, an electrolytic copper refinery, a precious metal refinery and a copper rod
plant. The distance between this complex and the La Caridad mine is approximately 24
kilometers. Copper concentrates from both Cananea and
La Caridad are shipped by rail to the La Caridad smelter where they are processed and cast
into copper anodes of 99.2% purity. Sulfur dioxide off-gases collected from the flash
furnaces and converters are processed into sulfuric acid, at two sulfuric acid plants.
Approximately 2% to 3% of this acid is used by our SX-EW plants and the balance is sold to
third parties.Almost all of the anodes produced in the smelter are sent to the La Caridad
copper refinery. The actual installed capacity of the smelter is 1,000,000 tons per year,
a capacity that is sufficient to treat all the concentrates of the La Caridad and Cananea
mining complexes. The amount of smelter copper concentrates was 894,735 tons, 723,984 tons
and 684,806 tons for 2005, 2006 and 2007 respectively. The anode production capacity is
300,000 tons per year and the 2005, 2006 and 2007 production was 282,412, 242,410 and
204,354 tons, respectively.Sulfuric acid production was 833,380 tons, 670,535 tons and
674,250 tons for 2005, 2006 and 2007 respectively. |
