May 02, 2017· I'm glad I saved all of my left overs. I purchased a Blue bowl and ran in three different runs, +30, -30 and -100. Not only did it separate the -100 from the black sands, the amount of gold that the Black Magic lost in the -30 to the -100 range was eye opening. The Black Magic is put away and waiting for a buyer.
Have been told there are ways to use certain chemicals to help break down black sands, then cook it and kiln it to make a Dore bead. Have sands with gold, silver and platinum but is very fine and is attached in the sand unless it is ground up. Any help would be great!

Finding gold in the clay or sand of rivers, creeks and streams doesn't have to be as difficult as you think it might be. Keep at it, practice the right methods, and those nuggets and flakes will eventually come to you. More than anything else, though, you need to remember to have fun.
Both magnetite black sand and hematite are oxides of iron. These are rather complex inorganic compounds that can occur in various forms. There can be valuable metals in black sands that are magnetic – for example, some of the platinum group metals can exhibit mild magnetic qualities.
May 08, 2008· 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.

Once all the black sands are gone, you can pick out the pieces of platinum if present, and separate them from the gold. Pour the gold into the same gold sample jar used in the earlier steps. This dry process (Steps 1-7) goes very quickly if an effort was made during the final wet stages to get as much black sand and other waste material as ...

The flux protects the crucible, allows plasma arcing to occur, and refines the gold processed to a higher degree of purity. When firing, black sands concentrates, iron oxides, etc. are held in suspension by the flux so that the precious metals can be separated and poured into the mold as liquid metal.
Nov 24, 2015· I believe a good shaker table should separate the platinum with the gold away from the black sands. There spots on the Fraser River that have a fair bit of platinum and I know one commercial operation uses jigs then shaker tables to recover the gold and platinum.
Jul 03, 2015· 1. Blue Bowl Technique – This method of black sand gold separation actually works by using water in a similar fashion as a swirling toilet. It washes out the black sand and tends to keep the now cleaner gold at the bottom of the blue bowl. This is a really slick device, and is …
Your average "dirt" with small stones etc. has a density of about 2-21/2. Gold has a density of 19.3. The thing that drives us all a little crazy with black sand is that it is relatively easy to separate the "dirt" from the gold but most of us find it much more difficult to separate the gold from the black sand.

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 too much is present, it is a nuisance in filling the riffles of a sluice-box. The specific gravity of the minerals that compose black sand ranges between 3 and 5. Crude gold's gravity is 15 to 19, and crude platinum 14 to 19. The gold and platinum particles exist generally as …
Jun 28, 2020· Place a magnet on the bottom side of the pan and slowly move it around the pan. Black sand is magnetic and will be attracted to the magnet. This process will quickly separate the black sand from the gold. If you choose to use the magnet, you can either scoop the trapped black sand out, or use a gold snifter bottle.
Note that this principle doesn't work as cleanly when piles of black sand or other non-combustible materials are exposed to high heat. However, extreme high temperatures can cause small particles of gold and other precious metals to "glob" and bind together, where they can be more easily separated from surrounding materials and reclaimed.
One of the easiest and most inexpensive ways to separate gold from dirt is through panning. This age-old technique has been around since the Gold Rush, and makes a great outdoor hobby that can pay for itself. With a minimum of equipment, the beginner gold prospector can separate …

Black sand concentrates are what you end up with after first processing of your gold bearing material. It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of 5.26, an iron mineral that is non-magnetic and Magnetite, Fe3o4, with a specific gravity of 5.20, is magnetic.
