Talk:Bingham Canyon Mine

message: ::"Ore is loaded into a fleet of 64 very large dump trucks which each carry 255 tons (231 t) of ore at a time, at a cost of approximately US$3 million per truck."
It is unclear to what the cost of $3 million refers. Is it the cost of the truck? Or value of the ore that it carries?  Or the production cost of that ore?  This needs to be verified and reworded in a more straightforward sentence.--Edgewise (talk) 14:49, 21 April 2008 (UTC)

message: According to Carlos Ruiz Fuller annd Federico Peebles, both highly respected professors in the geology and geophysics departments of the University of Chile, Chuqui's copper production to the end of 1985 was 15.7 million tonnes (Yacimientos Metaliferos de Chile).  Since then it has mined an additional 13.6 million tonnes according to Cochilco (Comisión Chilena del Cobre), making a total of just over 29 million tonnes of fine copper.  If you still don't believe me, in The Decline of the Copper Industry in Chile and the Entrance of North ... By Joanne Fox Przeworski, are given production figures for Chuqui up to 1930 of 1.1 million tonnes.   Nevertheless, adding this tonnage to the 1986-2007 figures from Cochilco they nearly equal Bingham Canyon's claimed total.  Adding in the approximate 200,000 tonnes p.a. production between those two dates gives 26.3 million tonnes.  Finally, in a presentation entitled TRANSITION FROM OPEN PIT TO UNDERGROUND MINING AT CHUQUICAMATA, ANTOFAGASTA, CHILE given recently by Codelco executives in Johannesburg it was stated that Chuqui had produced by the end of the year 2005, about 2.6 billion tons of copper ore with a mean grade of 1.53% or 39.8 million tonnes of contained copper.  Assuming a rather low recovery of 75%, this equates to a production of just under 30 million tonnes.
Chuqui is the biggest copper producer in total, I'm afraid, and by a long way.  If you disagree, please let me know.Egoli (talk) 11:48, 13 June 2008 (UTC)

message: "A train in the background can be seen taking material to the dump." No it cannot be seen. I looked at the high resolution copy of this image, and I could not find any sign of a train in any part of the photo. So even if it is there it cannot be seen.

Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia.
This, however, doesn't necessarily mean it's spam, or not a good link.
If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting.
If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page.
If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta.
When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags.
The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true.
Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.
