Hard-rock mining generates more toxic waste than any other industry in the United States, according to the Environmental Protection Agency. NYT

As for sticking to something I know more about, trust me, it is more then you have, it is more then cheese, my wife has worked for 45 years in various positions up to and including executive row at one of the largest manufacturers of mining shovels

Oh my bad, my memory is not as sharp as it used to be:
Bingham Canyon mine was the fourth-largest gold. producer in the United States. utah.gov
Bingham Canyon is also the world's 4th largest gold mine, so you really don't look into things before opening your yap, ehh?
Originally posted by shotsThen go on to list the largest open pit mine in Bingham Canyon passing it off under facts about Gold when it is a copper mine DUH!

I haven't seen the assay for Pascua Lama, but I am sure it would contain arsenopyrite and other arsenical ores, Sofi.

My point is that the quantity of arsenic generated as a byproduct is relatively miniscule compared to the amount imported to the local environment for use in processing.

It's has been my understanding that arsenic is a byproduct of gold mining. I have not seen this process that uses refined arsenic for gold extraction. You sure you don't mean cyanide or mercury?

Gold sulphite electroplating solutions and methods
The use of arsenic as an additive in combination with a carboxylic acid in electroplating bath solutions is known from U.S. Pat. No. 3,776,822. In that patent the gold is utilized in the form of an alkali metal gold sulfite complex, and according to the patentee the combination of the foregoing components in the electroplating bath provides gold deposits with controlled hardness values below 130 Knoop. The metals which may be added to the bath include arsenic, antimony, selenium as well as tellurium. These are provided in the form of their soluble salt. The polycarboxylic acids employed by the patentee include succinic, malonic and oxalic acids as well as their derivatives such as maleic acid. The preferred combination of a polycarboxylic acid and "semi-metal additive" is oxalic acid and arsenic trioxide, respectively. However, the use of arsenic as an additive has certain disadvantages in that it readily oxidizes from the trivalent state to the pentavalent state at which time its usefulness as a brightener/grain refiner ceases. Furthermore, the control of such electroplating bath solutions is very difficult. Conventional analytical procedures only determine the total arsenic content of the bath and do not distinguish between the active trivalent state and the inactive pentavalent state. Thus, despite the fairly developed state of this art there is still a problem to be solved insofar as it would be desirable to have an easily analyzable system where the alkali metal gold sulphite eletrolyte consistently produces a pure, bright, soft gold deposit.
In summary, gold metal deposits from non-cyanide complexes such as alkali metal gold sulphites tend to be hard, e.g. 140 Knoop, when using either thallium or arsenic salts as brighteners/grain refiners. Without these grain refiners, the gold deposits tend to be powdery and of little use to the electronics industry. Nevertheless, the hardness of the gold deposits with either thallium or arsenic metal additives give deposits having hardnesses unacceptable to the semiconductor industry, which generally requires a gold metal purity of about 99.9% and a hardness value below 90 Knoop.

2. The premise of this thread, e.g., "G.H.W. Bush Gold Mine" has been legitimately called into question, and seems to be a ploy used for misdirection. The article alleges he "exerted pressure" in other countries on behalf of Barrick Gold mining. It makes no claim of a direct connection between Bush 41 and this mine whatsoever. So why call it "G.H.W. Bush Gold Mine", other than to mislead?
3. If I'm wrong to see it that way, I invite any member to post some credible evidence supporting claims that George H.W. Bush has a role in the ownership or management of this company. If I'm right, then referring to the mine this way is deliberately misleading.

Seems arsenic - and other elements - are used as "grain refiners" when processing gold for use in the electronics industry. So glad to know it wasn't another Alzheimer moment.
Barrick Gold has been accused of a number of environmentally unsound practices, as well as illegal trading activities. These include the proposed use of cyanide leach tailing dams for its gold mine project at Lake Cowal, the release of at least seven tons of mercury during 2004-2005 at the Super Pit gold mine near the city of Kalgoorlie-Boulder, Western Australia. wiki

But -- and just giving my opinion -- I think the "poppy picture" is 'shopped.
File photograph shows 10-year-old Pashtun boy Zinuallah standing near a poppy field, while on his way home, near the outskirts of the southern Afghan city of Kandahar on April 9 last year. Afghan President Hamid Karzai, who is currently on a visit to the US, on Sunday rejected US criticisms of his anti-drug efforts and called international help in the fight ``half-hearted.''
