<p>[QUOTE=&quot;desertgem, post: 1401108, member: 15199&quot;]The only way that refiners could be getting .999 gold, is if a large batch of .999 coins/objects were being melted. Gold does not occur in such purity in nature. Most alluvial gold averages about 75-85%. Some gold in quartz deposits (veins) can be higher, but usually less than 90%. To get .999, the gold is often treated with cyanide which separates the gold and then it goes to the smelters, where temperature and fluxes can allow the % to be raised to a higher level. This is why gold and silver at the 90% level was the normal until equipment and assaying jumped ahead.[/QUOTE]</p><p><br /></p>
