Talk:Broken Hill ore deposit

[Untitled]

I don't think the categories of this page are correct. The page is about the geology of the ore bodies worked by Broken Hill's silver, lead and zinc mines not the mines themselves. Does anyone else agree? Iain Stuart (talk) 06:43, 1 February 2008 (UTC)

I agree. What would you want to change it to? Rolinator (talk) —Preceding comment was added at 09:12, 1 February 2008 (UTC)

Historical production

The article says: "It is arguably the world's richest and largest zinc-lead ore deposit."

So, where are the dollar amounts taken out of the mine (s)? There should be a section detailing the amounts of the minerals mined and the corresponding value.

History

Most of the history in the article is factually incorrect.

• It has been known for years that Charles Rasp's real name was Hieronymous von Pereira, but we can let that pass

• It is completely untrue that "Rasp reported finding massive galena, sphalerite, cerussite and other oxide minerals, but was most concerned with the galena, a primary source of lead". In 1883, Rasp thought he'd found tin. An assayer in Adelaide informed him he'd found galena, i.e. lead sulphide, with silver in it. Rasp wasn't interested in lead - he was after the silver.

• "His reports, believed exaggerated at the time, of masses of lead in the desert, soon proved true and sparked a 'lead rush' similar to gold rushes." There was no lead rush - it was a silver rush. The price of silver was artificially high because of US politics. Lead only became important after the silver price fall of 1893.

• "Mining has gradually moved away from the initial small prospectors" No, mining moved very rapidly away from the small prospectors, who couldn't survive on the field. By 1885, the companies Broken Hill Proprietary, South Broken Hill and Broken Hill North had all been formed. BHP paid its shareholders a million pounds in dividends in both 1890 and 1891. Broken Hill moved on to become a major zinc producer, pioneering new technologies in flotation and other methods of dealing with low-grade zinc ores, none of which is mentioned in this article.

• The water issue of the 1950s is completely out of proportion. The article Broken Hill has a much more coherent history and a better description of the real water supply history of the field, involving a system of dams, pumps and pipelines.

I think these sections on history and water are inappropriate in this article, which is about the ore deposit, and should be deleted. Peter Bell (talk) 01:16, 10 September 2012 (UTC)
