Nano Gold Found by Scientists
Written by WTJ on June 23, 2008 – 7:47 pm -Australian gold rush started in 1851 when Edward Hargraves and his colleagues found gold near Bathurst, New South Wales. It had a big impact on Australian economy and development.
Scientists had performed the dream which ancient Alchemists had dreamt — creating gold. The gold was not visible to anyone as it was in nano size. However nanoparticles of gold are only created in laboratories but not in nature. Nanosized were discovered in Western Australia by scientists. Scientists were searching for nano gold in nature to understand how geological processes transported and deposited gold. This understanding can help gold explorers to find the new gold field. Leader author, CSIRO’s Dr Rob Hough, explained that nanosized gold was common in environments where saline water interacts with gold deposits. The gold nanoparticles were not detected earlier as they are transparent to electron beams.

This nano golds were really hard to find, whew! thanks to science, Australia is now on it’s verge to discovering lots of gold and it’s history…
Thanks for this informative article..
Kudos,

complex gold has been known for many years until resently with the aid of the sem,tem electron microscope,these nano particles of gold and other metals are being found. I have extracted gold from samples that would not respond to standard assay methods,such as fire assay, nuetron activation cyanide, aqua regia, bromine leach, idione leach, thiourea, thiosulfate and a few more.I have tested tailings that showed very little gold to find out later after the tailing aged by mother nature, it would show an increase in gold in the tailing.
