Gold has a specific gravity of 15 to 19.3. These black sands will weigh a third (1/3) to a fourth (1/4) the weight of gold (Au). 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.

Where To Buy Magnetic Sand How To Process TheEmail with how many pounds you have available.How many of you have attended a gold show and watched with fascination as gravel is fed into a spiral gold wheel and the gold appears along the spirals then disappears into the center hole and lands in a cup?For those of us who process lots of black sand the choices on how to process the sand is limited to panning, using a "Micro Sluice" or a spiral gold wheel.After panning for many years I always ended up with back sand in the gold.ALWAYS! The micro sluices work OK but are slow and I still end up with black sand with the gold. Visit the following link to see more close up shots of various sands from around the world - pretty interesting.What other prospecting tools are there to clean up black sands?Besides the inexpensive gold magnet (see below) you can move up to a mechanical gold wheel or blue bowl.We need your black sands for testing new equipment! Sell us your black sand concentrates (with or without gold). Using a set of classifier sieves (see below) will help you greatly.Try one of our black sand magnets for quick and easy gold panning cleanup.And practice your clean up with one of our gold panning bags loaded with real gold.Just for fun: Picture above shows California Black Sand under a microscope. Without classification, gravel three times the size of gold will be recovered with the gold, hence the necessity for proper classification. Proper classification (sorting by size) is the key to fine gold recovery form black sands. Gold with a specific gravity of 15 to 19.3 and black sand at 5 to 6+, when classified to the same mesh size, will allow the gold contained to be easily recovered. Once the water flow is properly set, no further adjustment is required. Use wheel tilt to adjust pyramid, not water flow. The tilt of the wheel should be 45 degrees to start, water flow adjusted to an even flow without splash and the black sand pyramid adjusted to an inch below center hole. You should use Jet Dry®, at the rate of three drops per five gallons of water to prevent gold from floating out of the wheel. His answer then is as valid today was, "The wheel is only as good as the operator!" If you do not understand the operational theory of gravity separation, and understand the importance of classification of the gravel to be run into a 3 to 1 ratio then the results will probably be poor.For best recovery your gold recovery machine should have a green or blue wheel. Adobe photoshop full crackedBowl but Pioneer Mining in Auburn, CA acquired the patents and the molds and now it's just called the Blue Bowl (I can't imagine why). It used to be called the D.A.M. - BUY ONE BELOW -Of all the black sand separation methods, the Blue Bowl will probably save the finest gold without resorting to mercury or other chemicals. Also available is a micro adjuster for the older 13" gold wheels that allow micrometer like adjustment for near perfect gold recovery. The new agitator wheel, turquoise in color, will fit most all older 13" gold wheels and pay for itself in short order. It is possible to recover over 90% of the gold in your concentrate if your wheel is properly set-up and your concentrate is properly screened.The new age of computer designed gold wheels with built in agitators are well worth consideration.
