| Remarks |
The plant was
originally built by Monsanto as a single
absorption plant and operated by ASARCO, Corpus Christi, Texas, USA. |
1982
- The plant was orginally built for Rio Tinto in Huelva, Spain.
1996 - The plant was relocated to its present location
2000 - When Noranda Reactor installed, FCII was awarded job to upgrade the
acid plant |
|
|
| General |
ca 2000 - Reverbatory Furnace
replaced with an oxygen enriched Noranda Reactor.
2007 -
The operational upgrade, with an original investment estimate of US$58
million, will increase production capacity by almost one-third from around
290,000 tonnes a year of copper in anodes to 380,000 tonnes a year.
Sulphuric acid production will increase from 800,000 to 1.1 million tonnes a
year. In addition, as part of Xstrata
Copper’s commitment to being an environmental leader in the mining industry,
Altonorte will voluntarily invest a further US$14 million to install double
contacts in the new sulphuric acid plant, with the objective of increasing
emissions capture from 93% to 95.5%. This will take the total expansion
capital to US$72 million.
