Found this gold dust in 3 minutes

[reptwar1]

I live by the Arkansas river and dug out a crack in sidewalk, that is submerged when river floods. Literally took 3 minutes to collect this gold dust. It stuck to my dust pan, and I am wondering about ways to collect it. There are literally hundreds of more cracks for me to dig out. Thanks in advance

Sorry, I wasn't clear. Wasn't meaning to use oil/Crisco on the matting. Just use the matting bare. Could have some cinder blocks or big rocks to hold the boards/matting in place while the wave action washes the lighter material away - just like a gold pan. Sorry, never been to the beach either....except for one very short trip to the Texas Gulf Coast at Galveston. The Pacific should be quite another story altogether!

We are talking about a method using oleophilic adhesion that is the reason for oils or grease....gold sticks to them but releases when heated enough to thin the oil so the oil floats to the surface of the water and the gold drops with a little encouragement by stirring or gold bearing greases can be burned off. The major plus factor is the resulting concentrates are mostly gold as opposed to most other basic concentration methods. This method is not meant for larger gold and beach sands usually don't contain any.

Well actually fish sauce has a lot of oil in it. I lit in on fire last night with a Propane torch. I'm thinking of doing a evaporate reduction test on the fish sauce to see if it is economical. $50 of fish sauce is not a big deal really. I guess I could make myself enjoy it.

So I'm thinking. A possible cheaper and environmentally better idea than crisco would in fact be peanut butter. I found a 24 pack or 1lb jars on sale for 50c a case!!!! I don't have any peanut butter to test at the moment but the creamy stuff should spread fine on a sheet with a paint roller.

What do you guys think?

thats because you nebulized the oil in it using the torch there is oil in it you turned into a gas and it burned...it is mostly water

Oops not 50c a case I meant jar... Roughly 24 lbs of peanut butter for 12 bucks!

So, howdoya (yes, that's one word) get the gold out of the peanut butter?

Eat it.

The oil will stick to the gold and float. The gold will not drop by heating and stirring. You have to incinerate or use a solvent or degreaser or dish soap ect.

Can you use a pump at the beach where you are going?

The fish oil works on burlap but I do not know how well it would work on plywood or any other flat surface. I think crisco or grease would work better on a flat surface. A very thin skim coat is all that is needed.

You can get a 5 gallon bucket of grease for about $60.

It is gold that you are after. The expense of whatever you use to coat is a minimum expense if there is gold.

Well how you you get the gold out of crisco?

 

[HMiller]

Maybe a deep fryer. Then glass snuffer bottle.

 

[ecmjamsit]

Feed it to a dog, then pan it later.

That's gross dude. Sounds like cheech and Chong mining methods

Not if you have a Golden Retriever.

If I remember right that was Labrador. I'll bet some fish oil would extract it properly. Administer 2 tablespoons per pint of peanut butter.

Well this thread has degenerated to the point of uselessness..............

Now just a waste of bandwidth..............

 

[HMiller]

Exactly.

For a preface...My little test session did not include final cleanup but I could see about as much gold as I would expect to find by panning about a tablespoon of minus 100 mesh concentrates that was caught in the petroleum jelly/vaseline coating on the 5x5" fiber board used for the test and there was more gold than the stray few pieces of non gold. Forum member Goodguy mentioned pet. jelly on another thread so that is why I used it. I thought I read somewhere that the gold would drop in simmering water but a solvent, etc. would probably be easier. No pumps allowed on beach but ok above the vegetation line. Moot point for me since I don't use one.

Out of here since it is getting weird....again.

Petroleum jelly aka Paraffin wax works as does coal tar and a lot of other things.

Yes it is getting weird as usual.
