May 01, 2014 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. Is It Worth Extracting Gold from Your Black Sand? Again, the answer is, it depends

As gold miners, we take advantage of the superior weight of gold to separate it from other materials. And while this works perfectly when it comes to separating light materials from the much denser gold particles, it becomes more and more challenging the heavier the materials we are working with. Once we find black sand, we have managed to concentrate the very heaviest materials, which sometimes
