Tambang emas terbesar #1 dan tambang tembaga terbesar #3 di dunia, meskipun namanya Grasberg, tambang ini terletak di Indonesia, tepatnya di sebelah Puncak Jaya di Papua. Karyawannya berjumlah 19.500 orang dan dimiliki oleh Freeport-McMoran dari Amerika Serikat. Tahun 2006, tambang ini berhasil memproduksi 610,800 t tembaga, 58,474,392 g emas, dan 174.458.971 g perak.
Tambang ini terletak dekat dengan glasier pegunungan tropis yang sangat jarang yang berperan sebagai indikator perubahan iklim di daerah itu. Pencuraman bukit karena aktivitas pertambangan, juga gempa bumi dan curah hujan yang sangat tinggi, menyebabkan longsor mematikan di daerah tambang.
Sementara proyek reklamasi lanskap telah dimulai di tambang itu, kelompok lingkungan dan warga lokal mengkhawatirkan kemungkinan kontaminasi tembaga dan drainase batu asam ke sistem sungai sekitar, permukaan tanah, dan air tanah. Freeport berkilah bahwa apa yang mereka lakukan sesuai dengan standar industri, dan telah disetujui oleh lembaga survei.
Freeport dan Rio Tinto telah dikeluarkan dari portofolio investasi Dana Pensiun Pemerintah Norwegia, pemberi dana pensiun terbesar kedua di dunia, karena kerusakan lingkungan yang disebabkan oleh Tambang Grasberg. Saham senilai US$ 870 juta dikeluarkan dari pendanaan ini sebagai akibat dari keputusan Norwegia.
Akankah Puncak Jaya kehilangan saljunya sebagaimana Gunung Kilimanjaro?
Largest gold mine # 1 and # 3 largest copper mine in the world , despite its name Grasberg mine is located in Indonesia , precisely next to Puncak Jaya in Papua . Employees amounted to 19,500 people and is owned by Freeport - McMoRan of the United States . In 2006 , the mine was able to produce 610.800 t of copper , 58,474,392 g of gold , silver and g 174 458 971 .
I wonder what caused this mine ? Though it is located close to the peak of the highest mountain in Indonesia .The mine is located close to the tropical mountain glaciers are so rare that acts as an indicator of climate change in the region . Pencuraman hill because of mining activity , and earthquakes are also very high rainfall , causing deadly landslides in the area of the mine .
While landscape reclamation projects have been initiated in the mine , environmental groups and local residents concerned about the possibility of copper contamination and acid rock drainage into surrounding river systems , surface soil , and groundwater . Freeport argued that what they are doing in accordance with industry standards , and has been approved by the pollsters .Freeport and Rio Tinto have been excluded from the investment portfolio of the Government Pension Fund of Norway , the second largest pension fund providers in the world , because of the environmental damage caused by the Grasberg mine . Shares worth U.S. $ 870 million was issued as a result of this funding from the Norwegian decision .Will miss the snow as Puncak Jaya Mount Kilimanjaro ?
