A year or so ago I read a post about some reasonably priced classifiers that ran all the way down into the 400 mesh range. I wrote all the information down and now cannot find it anywhere. I've spent several hours searching these posts and still no luck. Does anyone remember this or know where I can purchase 200 to 400 mesh screen or premade classifiers in that size range? Thanks.

Reminder you can't post links to non supporting vendors that specialize in items sold by supporting vendors.

Thanks everyone for your replies. Sorry, I didn't realize asking this was going to cause anybody to violate TreasurenNet rules. I wasn't aware that any of your supporting venders offered 200 to 400 mesh classifiers.

Gotta ask..why do you feel the need to classify all the way
down to 400 mesh? You'd need a decent magnifying glass
just to see it at that size.

I'm in Illinois so there isn't a lot of gold in my area over 100 mesh. Not visible to my naked eyes is a very very large amount of micro flakes that I can only see with a loupe. I am planning on using my rock tumbler as a small roller mill and just do some experiments to try and isolate some of the micro gold from the cons. I will probably end up purchasing a retort and use mercury to capture the micro flakes but I think it will be interesting to play around with different options that the small mesh size might help me with.
 

I love looking at gold under magnification and all it's beauty. Gold is Gold no matter what size.
 

Those are nice Kev but 120 is the finest he wants 400, which I couldn't find. My post/link got down to 325

Actually you are confused by these being labeled in micron sizing instead of mesh. They really do go small 60 micron is 240 mesh. The others are 125 and 170 mesh. Yours goes smaller for sure but these are the least expensive below 100 mesh that I've ever seen!

KEV the mesh on the ones you listed seems fine. I was just glad to see they were multi purpouse...

Just out of curiosity....What is the smallest mesh size of the classifiers you now have? The reason I ask is because there have been some posts on this forum where people have under or over estimated the screen sizes of some of their pesky fines. Some of them were screening to only about 30 mesh much less to minus 100 mesh in the first place so they were having a hard time panning the mixed mesh minus size concentrates. I have found that screening one or two steps below 50 mesh (say 100 and 150) will usually facilitate panning to separate out the vast majority of the gold in many, though not all, scenarios. As an example, I mine ocean beach gold and virtually all of it is minus 100 mesh but most of it (in weight) is plus 150 mesh. I just save the minus 150 mesh to play with when I don't have anything better to do.

Good luck

I am not sure of the exact mesh size of my smallest classifier. Right now I am using a nylon coffee filter for my smallest classification. Best guess is 80 to 100 mesh.

Time for a little mercury action.
