janevictory Posted February 14, 2012 Share Posted February 14, 2012 Placer diamond mining, also known as "sand-bank mining" (top of page, right) is used for extracting diamonds and minerals from alluvial, eluvial, and or colluvial secondary deposits, and is a derivative form of open-cast mining used to extract minerals from the surface of the earth without the use of tunneling. Excavation is accomplished using water pressure (hydraulic mining), mechanized surface excavating equipment, or hand digging (artisanal mining).Diamonds and most gemstones are hard, highly resistant to weathering, and have a specific gravity that is higher than that of common minerals, rock or sedimentary soil, therefore, they tend to concentrate in alluvial deposits in the same way that gold placers develop. Gems are separated from waste material using various sifting and sorting techniques such as cone screens, box screens, or pans, which concentrate the heavier gems at the bottom, or sort material according to size.

GlennM Posted February 18, 2012 Share Posted February 18, 2012 Don, having a non-malicious, albeit commercial, link in a profile isn't a problem... I hope. Because I've got the shop's in mine. Quote Link to comment Share on other sites More sharing options...

Au Seeker Posted February 18, 2012 Share Posted February 18, 2012 You don't know that until you open it.SteveI have checked out Jane's link and it doesn't raise any red flags or set off any alarms, it would be gone if it was found to be malicious, it's a mining equipment website for large scale mining.That being said, I don't usually check out website links in member's profiles unless warranted as in this case, so it would be wise not to click on any links in anyone profile or post without using reasonable caution, this would include Jane's link unless you're sure of the protection installed on your computer.The programs I have allows me to check out any link, download, etc. for any malicious content before accessing, opening, downloading, etc.Skip Quote Link to comment Share on other sites More sharing options...

GlennM Posted February 18, 2012 Share Posted February 18, 2012 In those instances where I'm unsure - and I do have some serious protection as well - I copy the link and do a web search of the link. Google will translate most of the time and you can often tell if things aren't kosher by the short description. Quote Link to comment Share on other sites More sharing options...
