Again it is important to note that these are just starting points and not hard and fast rules.
Grinding Black Sands: Often the very fine gold contained in black sand can be literally locked up inside the sand particles called "micro-encapsulation" or simply stuck to the sand particle itself. A GPK user suggested this tip to use prior to roasting and it seems to work really well: Take a trip to the thrift store and pick up a used blender.

If you have gold that is mixed with other materials then it would be best to mix flux with it before smelting. Use two pinches of flux per ounce of gold jewelry and more for dirty gold scraps. If you are going to use the potato method just add one pinch of borax into the potato hole before melting the gold. 4. Melt the gold by using a torch.
When you mix the finely powdered gold-bearing rock with some mercury the gold within the rock dissolves and forms what& 39;s called a gold amalgam while the rest of the rock is left behind.
THE PROCESS: When your black sand concentrate is thoroughly mixed with the flux and put into the crucible and inside the kiln the flux and precious metals melt and the impurities are taken up by the flux and suspended so that you can pour the smelted precious metals from the mixture after sufficient temperatures are reached inside of the crucible.
Sure. It’s called refining. Some people use acids to dissolve all the metals into a solution and then precipitate out just the gold out of solution. Nasty chemicals.
Use Flux. Flux is a mixture of borax and sodium carbonate. It helps for gold melting. You can mix it with gold dust before melting or during melting. Oil the mold hold and should be preheated. Use ammonium chloride on gold after gold pouring. It will give shine. Last and bonus tip is that Select any portion for gold melting then fix it for

They also allow people to mix metals together such as gold silver copper aluminum and so on and melt them at home. To use them you will need the same equipment including a crucible and flux. If the gold item also contains small percentages of silver copper or zinc the melting point will be lower. 7
If the gold and platinum are "free" IE not tied up with refractory minerals like arsenopyrite by far the simplest way to separate gold and platinum from black sand is by gravity. There are many types of sluice boxes and spiral jigs commercially available or you can build your own. Or you can use a shaker table.
Going over it multiple times will concentrate the gold. However if I only get to pick from those three options I& 39;d go with the furnace. Gold melts at 1064 C magnetite melts at 1538 C. The gold will melt before the magnetite does so all you need to do is provide some way for it to flow out and be captured.
ASSAY PROCESS Because of the thickening process as just discussed 30 grams of starting ore is clearly too much ore. Also because of my earlier work on x-ray analysis of reduced magnetite I became convinced that the black sand contains a very high percentage of platinum group elements—in the neighborhood of 10%.
Collect the powder into a crucible or melting dish. Apply heat with an oxy-butane torch from the side of the dish toward the center so that the powder melts at 1947 degrees Fahrenheit. Remove the heat when the gold has melted completely and allow it to cool. Once cooled the gold is ready for fashioning into ornaments.
In any case I would concentrate the values before attempting any smelting process smelting black sand with little gold your gold will likely just be lost in the slag in small beads if your lucky. Smelting gold with very little black sand involved would work better to form gold button with a slag iron glass on top.
The gold in the crushed ore was rather large and chunky and there was virtually no black sand in it. I had expected the sluice to do well with the ore. A more real-world test would be to see how it handles fine gold mixed with black sand like what it would be seeing if I fed it gold-bearing stream gravel.

This released the sulfur into the air and left behind an oxidized black sand. Here is the magic bullet of the misunderstanding: the black sand was cooled and then mixed with copper ore and heated to create copper matte or exposed to a lixivant: either cyanide amonium thiosulfate or hypoclorate salt solutions.
Decrease% of gold to < or = 25% as low as possible by copper or silver. Then put in 35%-40% HNO3. Wait 1 or 2 hr filter solutions with filter paper. Rinse well with D.I water. The black powder is gold. Dry it and melt it and you have 99.9% gold this way without the iron inside the metal.
The black sand beaches of Lake Superior are one of the most consistently rewarding prospecting spots in all of Wisconsin. Running through Douglas County Lake Superior is the largest of the Great Lakes of North America. It should then come as no surprise that this lake boasts more placer gold than most other bodies of water in Wisconsin.
If your assay shows values for gold at almost 13 Troy oz./ton there would be assuming a specific gravity for magnetite black sand of 5.0 roughly 64 Troy oz./ cu. yard of black sand. IF there is a layer of clay below your placer it will ch all of the migrating gold in a layer approximately a few millimetres thick on the clay& 39;s surface.
