take a ziplock bag =put a magnet in side it --close the ziplock bag --and then skim it over the black sands --the black sand being magnetic will fly up to the bag / magnet combo-- and with gold being non magnetic, the gold will be left behind * -- once done =-- pop the seal on the ziplock bag and turn the ziplock bag "inside out" thus removing the magnet from the bag and yet trapping the black sand inside the the fliipped bag (what was the "outside is now its inside -with the black sand rapped inside it ) tah dah.

There have been posts mentioning that those sands contain other PM's, like Platinum, gold, etc. I thought you are supposed to roast them then toss cold water on them to crack them open and pull out the PM's. I'll let the experts chime in on this though.

Yes, you can do all of those things; however, you need to know what your black sands are carrying first. You can either pay for an assay, or if you're lucky enough, research one that's already been done for your particular area. Then, you'd follow the recommended procedure to liberate (roasting, crushing, amalgamating, leaching, etc.) the gold and other precious metals from the black sands.

My partner had a bunch of black sand that he'd been lucky enough to find the reports on for the area. He had to roast them, then crush them, then tumble them to a fine, fine powder, then amalgamate just to get the gold--after all that on his own, he didn't want to go any further to even try to recover anything else.

There used to be outfits that would buy bulk black sands from you (as long as they had certification of the area's history), and there were other outfits that would process them (probably still are), but then you had to pay them.

All the best,

Lanny

I cant help but post a reply here.I am a placer miner in B.C. and have to laugh when I see people who really do not know of what they speak and yet offer answers to others. Black Sands can and do hold values in Precious metals.Not all black sands do but any taken from known mineralized areas such as gravels that contain placer gold almost always do. The value of the gold , silver and platinum can vary widely even on assays taken on samples from the same gravels. I have had four assays done on my black sands from my mine.I first remove all visible gold on my Miller Table and it is the leftover "tailings" that I sent for assay . They are all different which is to be expected. They range from a low of 188 grams or 6 ounces per ton gold to a high of 2449 grams per ton gold and 206 grams silver per ton. That is just under 80 ounces of gold and 6.5 ounces silver per ton of black sand. That is a dollar value at todays prices of $132,500. per ton. Considering a ton of black sand can fit into 8 five gallon pails I would say that black sands are a very valuable commodity and if you produce more then a few pounds should never be discarded without paying the $80 for an assay. And yes I do recover all kinds of gold from my black sand tailings.Here is my last assay. assay dec 2012.jpg

....................some are very valuable.......I know of one operation right now running belly dumps of it 400 miles to be refined...............................You cant get much of it in a belly dump either and stay within weight limits

My advice is - the majority of readers of this thread will be lucky to accumulate a 5-gal bucket of bs in two or three seasons, therefore, the cost of assays
and processing do not seem economical. I once had assay done on dredge cons bs and sure enough high gold content. But after trying to lug a half 5 gal.
bucket up 500 ft to truck - just dumped the other bucket - no regrets. At least wait til you have two or three full buckets before taking that step (or
PM prices double)

I can get more than 5 gallons a week in my dredge. Closer to two gallons a day. As for the economics of refining it, I don't know if it would be worth it. Never had them assayed.

.......you may be surprised?

Fullpan,you are so right.....most five gallon buckets handles can not hold much over a half bucket

I had a guy come by the house years ago wanting to buy straight Bs.I didnt know what to even charge so i said $1 a lb....he said fine and that he wanted at LEAST a five gallon bucket,and had $50......I laughed when I told him $50 was not going to get him a 5 gallon bucket!!He says...well whats one full weigh?I said I dunno try to pick one up........he strolled over all cocky and about pulled his arm outta socket when he went to just one hand lift it up!!! :laughing7:

Well, I might send some off to be assayed just for grins. The problem is transportation. Let's say my BS assays well, then how do I transport hundreds, or thousands of pounds to a refinery willing to buy it? Transport cost and time could easily depreciate the majority of any values.

Yep,that is why I dont even fuss with mine.......I looked into having mine shipped by my bud,I mentioned but keeping them seperate is just too big a PITA!
