Correct Gold Slurry Sampling Design Critical To Accurate ...
Firstly, the gold is found in such small quantities (ppm) in slurry samples, and has a very high specific gravity of 19.3g/cm 3. In addition, the gold particles are extremely fine, with measurements of typically less than 20 μm in many instances. Gold will easily segregate and find any opening or crack available to settle and elude detection.
