Lots of myths and misunderstandings surround the question of black sand as you will discover if you search for the term on Google. But before you assume that your black sand is worth its weight in gold or even a tiny percentage of that here are some questions to answer.
Black sand can be sitting on a beach. It can be found in placer deposits of other minerals that occur naturally in streams river beds or as veins in rock faces. It can be a byproduct of mines that extract primarily copper zinc or another metal from the earth.
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.
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 separated by sifting or using a device called a shaker table or other specialized machinery. Do you remember the Gold Rush prospectors who panned for gold in streams They were engaging in just this process.
If gold is physically bound to minerals it can sometimes be separated by the application of heat in a smelting operation. At other times the only way to separate the gold is to immerse quantities of black sand in chemical baths a process called wet chemical extraction. The more complex the separation process the higher the cost becomes of extracting each troy ounce of gold.
Again the answer is it depends. If only a tiny amount of gold exists in a large quantity of black sand the cost of extracting it can be much higher than the value of the gold itself. If there is a lot of gold that can be extracted using sifting or other relatively inexpensive processes that could be an option worth considering.
The bottom line If youre sitting on a quantity of black sand of any kind start out by sending a sample to a qualified testing service. Consider calling Specialty Metals Smelters and Refiners at 800-426-2344 to learn more.
