I have a few old gold mines one has a reported vein just 10 feet from the surface, reported in the late 1800s when the mineral survey was done for the patent. the ores in the area are sulfide / pyuretic. (wishing for a spell check) Gold assays run from 2 tenths to 6 tenths an oz . Im not going to try any gravity methods.. I will try a very fine grind with a very low amount of natural oils (combination of almost any three should work) then put the grinds into a column of water with fine air bubbles (pgms and most of the good metals are hydrophobic) thus the metals will all float to the top. then a fine water mist will wash the gange and clay that may have also made it to the top washing it back down the column into waste stream. The pgms gold silver and a lot of other nice things being hydrophobic( afraid) of water stay attached to the air bubbles on top of the column and get vacuumed off to the concentrate container.
then just repeat until the concentration is over 20 oz per ton (goal). Next smelt or sell. Bryan In Denver Colorado.
