This is a picture of the dry tailings disposal system (fan shaped) at La Coipa mine as it looked like in 1994. La Coipa is a major silver/gold deposit located in Chile (Atacama region). It is being operated by the company Mantos de Oro, a Chilean company owned at 50%
in joint venture between GoldCorp and Kinross. (until recently it was operated by Placer Dome Cy).
The mine produces anually about 100,000 ounces Gold and 3,500,000 ounces Silver. "La Coipa"
The La Coipa deposit occurs in a very arid environment at 4200m altitude. This makes the environmental monitoring a real challenge. Not only are cyanide emissions to groundwater strictly controlled but the natural mineralisation has also a high mercury content that is remobilised by the exploitation and must be prevented to leach away.
Another view of the open pit can be seen in a "previous picture"
Locate the few buildings and the red car at the right side of the picture to get an idea about the scale of operations ! |

Bonsoir Eric,
Tu présentes de sujets très intéressants, mais tes deux dernières images manquent de relief. Est-ce le résultat brut du scan ou celui de ton PP ?
Merci pour ce bon document.
Amicalement/Pierre

Bonjour, Eric.
Personnellement, je trouve la compo de celle-ci assez bonne, et si la réussite graphique n'est pas parfait, il s'agit plus d'une conséquence de la qualité du scan et d'un retraitement peut-être un peu léger (mais je comprends que tu puisses répugner à pousser trop le post-processing).
est-ce nécéssaire de rajouter que je trouve le sujet (et la note) des plus intéressants.
Merci du partage.
Hi Eric,
The angle of the shot taken was very nice. I don't know whether you could have increased the exposure or not. Otherwise, the photograph was very nice alongwith the good bit of information.
Regards,
Sourav.
