How To Identify Gold Ore (Tips and Scientific Tricks)
Determining the specimen's density is one of the first steps in recovering gold from gold ore. Knowing the density of the ore makes the process more effective. The density of gold ore varies from one type to the next. Typically, impure gold is around 16 to 18 times heavier than its associated host rock, which has a density of 2.5.
