How to test for gold in quartz crystal
Then send it to an assayer. The higher the gold concentration in the sample, the better the accuracy of the result. When the assay result is returned, multiply the concentration they provide by the crude weight divided by the weight of the concentrate you sent them. That will give you the concentration of any gold in your raw sand. Good luck.
