Ok. So, I gave this a try. Wasn't terrible, but the best result that I could achieve was to reduce concentrate volume by a little more than half. Seems like I hit an inflection point where there was a tradeoff between removing more black sands or losing some fine gold. The lightest/most fine black sand material washed out very nicely but I ran into the aforementioned problem once I needed to adjust water flow to start removing coarser material. ...Perhaps, I just needed to spend time tweaking things to get desired results.

Might give it another shot at some point in the near future. I don't have a blue bowl or other such equipment, so would be nice if I could use this much less expensive approach.:occasion14:

You will probably get better results with closer classification eg. minus 30 plus 50, minus 50 plus 100 and minus 100 mesh. Over 30 mesh is usually easy to pan. The gold is greatly advantaged when it is processed with only like sized material since it is about three times the weight of the other individual particles. Here is one source for them.

Good luck.

Kind of the same principle of the blue bowl combined with a little different take on KevinInColorado's method of gold separation with a soap dish....your inspiration Kevin?:dontknow:


His first part is like the dynamics of a blue bowl and the last IS like what I do!

I don't own a blue bowl or miller table. I was just taught by a 71 year old guy that has been panning since Jesus was a teenager. LOL
