Hello everyone. I'm in a pickle and really could use some advice. I have about a 1/3 cup od classified (20 mesh) material left. Any gold left is microscopic but under a magnifyglass I can see hundreds and hundreds of specs. I don't know the sizes but -200 to -500 ( let's just say... Too small to see without magnifyglass). The problem.....there is no more black sand and the material is probably 60-70% garnets (of all sizes) which are heavier than the gold so impossible to pan. I have a super concentrator sluice with shallow v matting and a home made Miller table. Which one should I try to help? Either? Both? Thinking the gold would Washout before the garnets in the Miller table. Would love to get this gold.
What works for me. I bought a set of 6” screens that I use to screen my material to -20, -30, -40, -60 and -100. I then run each batch of screened material separately on the miller table. Adjust the angle and water flow so that the gold stays and everything else moves off.

if you can see it you can get it 1 way or anotheri would run it through some mercury then retort it faster and easer

Use the miller table, what do you have to loose, it a captive system. Mine catches 200 mess gold nicely.
