Awesome reply, thats reality. The ore is not mine, a close friend of mine is sitting on about 1/2 ton of this stuff in bags. I'm simply looking for the best way for him and me both to make a few coins on the side and maybe start a new hobby(you probably have some smart remark to say to that as well, well keep it to yourself thanks).

The origin of gold deposits has been the subject of considerable debate and remains controversial to this day. Most published ore deposit models in the literature to date involve gold being sourced from the mantle, the lower crust or the upper crust (Groves, 1993, Phillips and Powell, 2010, Thomas et al., 2011, Hronsky et al., 2012, Tomkins, 2013) transferred to …

This type of gold ore is suitable for TU/ETU leaching. The highest Fe-bearing gold ore was the most difficult to extract Au in ETU/TU leaching. There are at least two detrimental factors in TU leaching of Fe-rich gold ores, that is (i) the oxidative decomposition of TU, and (ii) complexation of TU with Fe 3+, which both cause to deduce the ...

Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).
