Human rights violations in large-scale goldmining
Open pit gold mining destroys large portions of fertile land and water bodies. Rural communities face involuntary resettlement, often without adequate compensation. Civil society organisations from all continents call on governments to stop irresponsible gold mining:Berlin Declaration 2005: stop irresponsible gold mining
For those that do not understand the issue, Wikipedia is not a forum for advocacy for any cause whatsoever -- it is a neutral provider of information. That means that it is not a place for people to try to recruit people to their cause, to explain how evil a particular industry is, how good a particular industry is, or anything else like that. All articles have to have a NEUTRAL viewpoint.
In this particular case, I would propose that the given section be altered to discuss the pros and cons of gold mining, explain the existence of controversy, and to provide links (without specific endorsement of any sort) to organizations on both sides of such issues.

replies: text: Much of that should probably stay within this article.  Be aware that much of that, ie consumers, comodity markets, etc, are very fluid, and not suitable for a detailed encyclopedia article.  We could have separate lists, however, similar to this one for gold mines and comapnies.   Turgan Talk 19:50, 13 November 2008 (UTC)
thread_title:  Information 

message: Logic says in syllogism - if water flows down-hill over rock, then eventually, the precious metal or mineral will wash down to the valley. Further, if the matter (gold & mineral) is heavier than water, then force and gravity will distribute the matter. Force (water current) will push the matter down the path of least resistance. Gravity will attract that matter to the centre of the earth. Therefore, matter is washed from the hills to the centre and sides of the water-flow. Stream tests (MacKay, B. R., Cdn Geol. Survey Mem. 127, p. 65, 1921) have shown that sediment will gather at the bend in the stream (water-flow) but (gold) accumulation, in the centre, is just Baer Law theory.

thread_title:  Salting a mine 

message: I saw a documentary on the gold mining in the amazon region some years ago. Vast environmental damage is done due to turning whole hill sides  into sludge as well as using Mercury to bind the gold in the pan. This way large amounts of Mercury get into the river, to a measurable extent downstream. The gold-mercury compound is then poured in something like a turkish coffee can to be heated in open fire to evaporate the Mercury. Sorry - this is all I remember Walter Hartmann 11:36, 20 May 2007 (UTC)
thread_title:  use of Mercury - Quicksilver in gold mining 

message: Mercury is not a very efficient way to recover gold, as the gold must be free of naturally-occurring vegetable oils and crusts such as manganese. In the old days, this was done using a ball mill and a mixture of chemicals to clean the gold. Often, blocks of wood with holes drilled in them were placed at the head (feed end) of sluice boxes and the holes filled with mercury, but a lot of mercury and gold was lost due to 'splashing'.
The device you may be thinking of is called a retort. The amalgam is placed in one end, and heated. The mercury evaporates, and is condensed to be used again. Many elements can cause a 'sickening' of mercury, reducing the effectiveness. DO NOT DO THIS!
Retorting gold can be dangerous, partly becasue of the fumes (Mercury fumes will kill you), but mostly becasue of the danger that the crucible where the Mercury is being heatet can cool slightly and the water in the rocovery end can siphon back to the very hot crucible and make it explode.  you need to know what you are doing to retort mercury. --N.M.Sheedy
Now as for the stupid theory that miners wantonly lost Mercury... I just have to shake my head when I read this false blather.  The idea that a great deal of Mercury was lost by miners is completely absurd.  The miners used Mercury becasue gold would cling to it.  If they were losing mercury, they were losing gold, and they did everything in their power to prevent this from happening--after all the idea of the whole process was to recover as much gold as possible!  As such, very very little mercury was lost in normal gold recovery operation.  In fact, looking at records of gold dredging operations on the John Day River and Middle Fork of the john Day River in the 20th century, the miners actually recovered MORE Mercury than they put into their collecion system... HOW? because Mercury is a NATURALLY OCCURING ELEMENT IN THE EARTH.  Mercury is heavy, and their recovery system actually collected thier own mercury, plus some natural mercury that was already in the river bed.  Moreover, I'll add that I have never heard of Mercury being poured into holes in sluice boxes while there is running water.  I've been around mining all my life (and my family has been mining gold for more than 150 years) and have never heard of such a thing.  The gold was recovered after the water stopped flowing in the sluice box by scraping out the gold and other heavy stuff that was collected by gravity and water flow in the ridges, grates and mats of the sluice biox.  The Mercury was applies to the clean up after this in another container, and the Gold-Mercury solution taken from there.  As such, Mercury rarely if ever touched a sluice box, and was rarely if ever in contact with flowing water.  Don't believe the claims that miners caused a great eal of Mercury pollution.  It simply is not true.--N.M.Sheedy  —Preceding unsigned comment added by N.M.Sheedy (talk • contribs) 20:55, 30 January 2008 (UTC)

message: I've removed a bunch of outdated material obviously taken from "Gold Deposits of the World" by William Harvey Emmons (1937). No credit was given as to the source (user contends that it is in the public domain) and thus amounts to plagiarism - credit is needed. The main problem is that the information is severely out of date including Irish Free State and Southern Rhodesia headers. The state of gold mining in 1937 would be of interest in an article on the history of the topic, but not very relevant on the current status of gold mining. Vsmith (talk) 15:31, 31 August 2008 (UTC)

thread_title: pollution caused

message: This is an important subject in the history of the world, and there is only a small mention of what the Romans did and some obscure aspects of their history with gold.
I would think that nearly every major civilization mined gold. The wikipedia article on gold is in fact a good place to start.
If the methods they used elsewhere were basically the same, then that should be mentioned, and there should not be any specific reference to a particular civilization, as it shows a bias (in this case a bit Western-centric). I suppose if there is something interesting about the Romans, that can be mentioned, but the way the article is written, it conveys that the only known history of gold mining is of the Romans.

thread_title: Gold Mining Industry

message: There are big differences between the small scale outdoor hobby of weekend gold prospecting that involves individuals, families, and their clubs and the large scale commercial gold mine operations around the world.   You can't really compare the two but it seems some editors try to mix the two and make the issue very fuzzy in order to get their emotional point across. 
The hobby prospectors are helping the environment by removing the toxic metals like lead and cadmium from the waters and agitating the stream bed on a very small scale like what happens after a rainstorm but only in a much smaller area.  Fish love the food that was once compacted on the bottom and fish love to spawn in loose gravel beds. Eighthcreek (talk) 04:31, 30 December 2008 (UTC)

thread_title:  It is impossible to know... 

message: This reference on the main page  "Dan Oancea – Carlin: Where the Train Stops and the Gold Rush Begins" (no. 7) is no longer accessible and so now it's difficult to provide a percentage of overall above-ground gold that the Carlin Unconformity produced. The page on the Carlin Unconformity gives an estimate that 70M ounces of gold was produced here which is approximately 1.1% of overall gold mined based on the World Gold Council's end-2019 figures of 197,576 tonnes (70,000,000 / 6,352,216,000 = 0.01102 or 1.102%). This is a lot lower than the 2.5% previously quoted on this page so either a lot more gold has been mined since this source was last accessed or the report was already quite old. It might be worth stating this figure as a value rather than a percentage, or removing this figure all together unless 1.1% is still a significant figure when it comes to global gold production from a single mine / mining area? I tried searching for the report myself but didn't have any luck in finding an online and accessible version of it (sorry if I missed an obvious trick in re-locating the inacessible article!).
