Gold Milling Process -Primitive and Basic - 911 Metallurgist

13-01-2016  Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said “ There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt throughout

Here Is The Correct Way To Effectively Recognize Gold Ore

07-12-2018  Gold ore does not usually have any shiny gold on the surface. Spotting it with the untrained eye does not always yield results; it’s better to try a jeweler’s loupe. Then it is possible to see flecks of gold sometimes. It is usually not possible to find gold ore with a metal detector.
