Talk:Gold extraction

message: a a My understanding is that a good deal of the mercury in gold ores today actually is from amalgamation.  It's not that amalgamation is used today, it's the fact that the old miners left a lot of mercury behind when they were going after the free gold 100+ years ago.  This article needs a lot of work!

message: In the section on extration from scrap electronics, the word "enectration" is used. I don't believe this is an actual word since the only search result is for this page. I would change it, but I'm not sure what is exactly meant by "enectration". CrinklyCrunk 14:50, 7 November 2007 (UTC)
replies: text: I've never heard the word "enectration" before.  Recovery of gold from electronic scrap has a lot of issues.  First, there's the obvious materials handling problems.  Circuit boards are difficult to move around my automated equipment, and shredding and separation are tricky.  The resins present in the circuit board present a lot of emissions (chlorinated hydrocarbons, VOCs, etc.) problems if the recovery method is pyrometallurgical.  There's a lot of other metals there too, particularly lead, tin, and copper, mostly in greater amounts than the gold.  The gold recovered from e-scrap requires quite a bit of further separation and refining.  Just some thoughts.  I don't have time these days to edit Wikipedia articles.  Hopefully things will slow down at work, and I'll get back to work on this fun stuff.BSMet94 20:41, 13 November 2007 (UTC)

thread_title:  Enectration? 

message: This article seemed to say almost nothing about what types of gold ore actually found, and which of the processes mentioned apply to which ores. I added a stub section about ores, which I'm hoping is roughly correct, but this needs expanding and it also needs tying in with the rest of the article. Presumably different processes are used for different ores? Anyway, I know almost nothing about this so I'll have to leave it to someone else! Matt 23:58, 8 January 2008 (UTC)

message: Hi, can someone explain the difference between Gold mining vs. Gold extraction ? For me these two articles are about the same thing and their content are not really different. Thank you Snipre (talk) 20:49, 19 October 2015 (UTC)
