Hi, I have managed to extract the gold out of black sand ( it was only 300gr black sand), I have get done assay result which it was shoving …
At no time did the magnet get closer than 3 ". The result was such that if you can imagine the results of when Dan just stuck the magnet into the pan, in his video, and pulled it out full of black sand with a little bit of trapped gold, exactly the opposite happened. The mass on the magnet was 99.9% gold, with a little black sand.
In some black sands I am told there can be a tiny particle per grain of sand of gold in as oxide.I always take samples home and soak it in jewelery cleaner overnight or electrolisize it and I have found several things like rhodium gold alloy and other metals that had a black patina like manganese and nickle (posibly platnum bearing).
Another gas-fired mixture tested by Champion was composed of black sands (100 gr), charcoal (300 gr), sodium nitrate (900 gr) and powered silver (500 gr). When an inductive furnace was employed, the formula needed to be modified: black sands (100 gr), charcoal (350 gr), sodium nitrate (150 gr), silver (50 gr), and copper powder (50 …
While many today may seek to invest in gold rather than hunt for new deposits, various sources of gold still exist for gold-hungry prospectors. One such possible source is black sand. We'll cover …
Still dont really know. Type in Gold from black sand and you will find lots of articles on getting it. I was also told, black sand and Iron is always found around gold, but gold is not always found around black sand. Heating up the sand in hot acetic acid (vinigar), HCl, crushing, Panning is useless unless well crushed.
The black sands can also be just like this nugget a lot of what you think is just black sand can be gold. So this is how you can recover it. Put all the black sands in a rock tumbler for a day or a few hours. This will clean the black growth off the gold. then just put your black sands in a plastic gold pan and fan it out. then roll a large ...
Hi I have a need for some magnetic black sand that you already removed all the gold that you could. I am building a completely unique system to remove any micron gold that may be left behind. If it works,I will return the gold to you. We do not have magnetic black sand in my area. pm me if you can send some. thanks john I got …
The answer is, it depends on the kind of black sand that you have – if it does contain gold. If gold is present in small nuggets or flakes that are not physically bound to minerals, they can sometimes be …
A great pre-mixed refining flux containing Anhydrous Borax, Soda Ash and a bit of Silica Sand. Excellent for refining gold, black sands, and ore concentrates! Use with our Chapman Flux Thinner for optimal results.
I am a placer gold miner from British Columbia. After recovering all visible gold from my concentrates I have sent three different samples of the concentrates in for assays. They came back at 83, 188 and 306 grams per ton gold still left in the concentrates. In order to verify the existence of...
What is the best, most accurate method to assay the precious metals in black sands? I super concentrate my sluice cons with a clean up sluice, then run the black sands on a miller table to get the very fine visible gold out down to -300 mesh. My neighbors at their placer mine have had their...
Black sand samples must follow a special smelting procedure due to they are difficult to melt at common temperatures. The fluxes to be used must be chosen with detail in order to avoid wrong …

One of the problems with using AR on black sands is that the black sands contain a lot of iron which causes co-precipitation of the values. So the first approach would be to remove as much as possible all of the magnetic iron. But also keep in mind that you can have non-magnetic iron that can do the same thing (loss of values to insitu reaction).
I am looking to buy sum Gold bearing Black Sand. Around #30-#100 bags. My e-mail is bmarvel@centurylink I am just one man with a couple of concentrators to put to work. awaiting your e-mail reply or from here looking for a on going thing. Bob.
I'm interested in buying unprocessed black sands. I've seen 2 prices thrown around, $0.10 lb. and $0.25 lb; I'm thinking $0.25 per lb., with me paying the shipping. Opinions, commentary, ideas? Cheers, Mike
To smelt black sands you need slag formers: silica (fine ground sand) dehydrated borax, soda ash You will also need a collector: Gold works best, silver works next as best, copper, brass, bismuth, iron or lead Some people use nickel carbonate. You pick the collector according to your budget and your ability to separate the collector from …
Due to this innovative leach, TCB can effectively process precious metal bearing black sands on a commercial level. Our process also allows us to effectively process silver, …
We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.
So, what is in your black sand and does it contain gold? There is no way to be sure without sending a sample to a qualified gold refinery. If Gold Is There, Can It Be Profitably Be Extracted? The answer is, it depends on the kind of black sand that you have – if it does contain gold. If gold is present in small nuggets or flakes that are not ...
But after all is said and done it comes back down to classified size of material to extract the smallest particles out of any ore material, if ya have a piece of 100 mesh gold and 30-50 mesh black sand, the amount of force it takes to remove the blacksand from your gold will indeed remove the gold along with it..... so size matters!
If your trying to smelt black sands your dealing with mostly Iron ore, some magnetic and some nonmagnetic, the iron is in various states, roasting will help to improve the ore somewhat. driving off acids and putting the ore in a better state for oxidation (or reduction). The flux would need to be able to get the iron and other base metals to form …
Very little of the black sand i concentrated down by repeated panning was magnetic either. Less than 10% for definate. Pic of the demagnetised black sand concentrate i recovered my gold from Apoligies about pics been in wrong place i dont know why its happening its driving me nuts Ive a couple kilos black sand and a couple kilos of …

The majority of small and big placer claim operations make the most from the micron/flour they extract out of the very type of black sands that I am providing. I have a nice library of books with black and white photos of what they were doing in the Alaska gold rush days from 1896 through the end of WWII.
People have reported that after they have removed all visable gold, even checking with microscopes to be sure that what's left is totally black sand, that gold …
It was from a crucible plugged with an internet flux. The material was a mix of blacksands and about 3g of electronic scraps recovered gold. There was no visible gold in the sands. The black sands had been concentrated down twice before firing. First in a cleanup sluice and secondly in a green bowl.
Would not even think of assaying (or refining) black sands. Hematite and Magnetite are ~ 5.1 Specific Gravity and when classified to within 4 diameters of Gold are not a challenge for me to pan off. ... As …
This tiny sample has no gold and now you know the weight of the black sand with no gold per one full measure. The rest is easy now weigh a few measure fulls of the b sand and it should weigh exactly the same as the no gold first measure of black sand. ...

John, If gold is not heavier than black sand it most likely is not gold, Iron sulfides can look like gold, they will float off in a gold pan, where gold will stay behind in the pan after the black sand floats away, Iron sulfide Pyrite is called fools gold, because many people have been fooled thinking it is gold. I do not know if you have pyrite or real …
I am trying to figure out the best way to process my black sands after they have been run on a finishing sluice and a miller table to get the visible gold out. I have had the black sands assayed after I have gotten the visible gold out and the assays have averaged at 60 gr/ton gold. A lot of the gold in the black sands is locked in the black …
Yep, that's what I've been doing. There's still a lot of black sand remaining that isn't magnetic. That could be broken fragments of a number of crystalline black minerals we have around the area to the north and west, where mica schists are plentiful and various combinations of zinc-iron, manganese and other metal sulfides and oxides …
What Is Black Sand? Black sands are concentrates of heavy materials that can be found in the streambed. These elements can be found near most creeks, rivers, or streams, but the composition of the concentrate might differ.. Usually, black sand concentrates are a blend of commonly found elements, such as magnetite, hematite, pyrite (Fool's Gold), …
