Glad to help.

Interesting. I will try to remember to give it a go tomorrow.

The double barrel is doing well...

You are most welcome.

That seems to match my experience. I can recover down to 500 mesh in an ocscillating Jig. 2000 mesh won't even settle in still water- that's what we are working on leaching now.

It makes a big difference when you have an ounce or more of Gold in suspension.

You're welcome

Remember that larger gold will not act in the same way as micro fine gold. When testing a new material always use both types of reveal: my tapping method AND the swirl type reveal that works for the larger gold. It changes at about 50 mesh which id about the size of table salt.

Once it gets small enough it won't settle for sure. A lot of gold in hard rock IS that small. Thus the hybrid system{ gravity separation for the (relatively speaking) big stuff and dissolution for the small stuff.

@@hardrockuniversity7283 In commecial production the fines from the Ball mill go thrugh a gravity separation process and only the fines go to the cyanide dissalution process. t's pointless to send large bits due to the time it would take to put them in solution.

@@cooljets Correct. Unfortunately, end discharge ball mills also tend to be good gold traps.

@@hardrockuniversity7283 The Gold isn't going anywhere. It just needs to be cleaned-out periodically. The super in charge knows when. It's the down-time that makes management ansy.

Loren said the mine he used to work at used the gold in the ball mills an an emergency piggy bank. 🙂

I have heard of Snake River powder.

Lotsa 200-300 mesh gold

@@frankbyrd6726 So I've heard.

Thank you

Thank you

You are most welcome

Very little heavies. Mostly tramp iron from the grinding. However, even a couple of percent heavies seems to make little difference. In solid heavies, the gold still seems to drop reasonably easily as ling as it's not flaky.

You always have to follow the numbers

Less than 15 seconds seems fine to me. To answer the other question, the thinner the pulp, the faster the trip to the bottom.

The problem is that when cleaning out the PAN after panning high grade cons, I can easily leave some gold behind that then shows up in the next test. If the cons are running 20 ounces per ton and I miss only 1% of the gold in the pan when I clean it, the next sample would look like .2 Oz/T even if it had nothing in it. That is why I started using different pans for cons versus ore. Not a silly question.

@@hardrockuniversity7283 oh ok thank you so much for explaining this….

@@juliesilva6760 You're welcome.

With a standard size sample, better than an ounce per ton. Probably 1.5 to 2 ounces per ton. If that was rock, it would be ore unless it was only an inch or two across.

I am pretty confident it would be even faster. I was surprised at how fast it was in those conditions. Common sense would seem to indicate it would move quite slowly, but not so much.

@@hardrockuniversity7283 - ever tried panning with some flocculant in the water instead of jet dry? I wonder if it would push sub 300-500 mesh gold to to the bottom, just like the other sediments.

@@danhodgins4015 I have used flocculant at times to settle the slimes in a process, but never tested it against gold itself. Might work.

Too expensive and too much hazardous waste for practicality. there are much cheaper and safer methods. It would probably work though.

Thank you. What would be a better plan of action in processing in your personal opinion. I'm learning from you

It is all ore dependent. First you would try a gravity separation is it is the easiest by far- IF IT WORKS. Then you would go to leaching. If you have sulfides you would almost certainly have to throw a roast in there between crushing and extraction. One always starts out with a serious sampling program and laboratory scale testing of the options BEFORE making any decisions or buying equipment.

@@hardrockuniversity7283 I have it as separated as it can generally get and semi concentrated, by the nature of this material it's a high concentration level. I wish I could post a video here for you if there's a way of doing it, let me know. I have three labs picked out for the assays which ones going to conduct two different test for me and I'm gonna compare which ones the most effective and cost effective for me when it's all said and done. I just after that don't know if I wanna go straight to refiner or bring a processor is a middleman and that's the purpose of that caustic soda question I mentioned if it's going to help me toward my end goal but if you have that process, you mentioned, please list it in terms of the lab in the other stuff you mentioned yes I got that pretty much dialed. In the fact I could probably bring this in now and I'll accept it the way it is with the smile on their face, but I wanna make them smile even further I want them to give me a better deal because I wanna make their life easier and I want to bring them enough material each week where they're happy as hell. I'm not a processor. It's kind of fun but I don't wanna get into it. I want to stay away from me wearing the refiner hat as well. I'm a rainmaker in mining, I find good gold, good buyers, good land and mineral resources, investors, and set up arrangements and turn around and do it over and over again, but this time I'm doing something a little bit different. It's hands-on only through the next step thus the purpose of my public question on one of these threads

That is exactly what happened here. Quick panning and then double panning the tailings will tell the tale for your ore. We have an ore up here where the gold is 80% passing 2300 mesh. Would not work for that.
