Precious Metal Ores, Gold, Platinum, Silver And Copper

Precious Metal Ores, Gold, Platinum, Silver And Copper

While a small amount of the free native gold in gold bearing ores is coarse sized, the greatest percentage is fine sized. These fine gold particles can be so small they are hard to see - some are even microscopic in size. The only other common form of gold in ores is when the gold combines with tellurium and other metals.

Oct 01, 2018· The term microscopic refers to substances that are very small, therefore, we cannot observe them without a magnifying device. Therefore, we need to use optical instruments such as magnifying lenses, light microscope, electron microscope, etc. in order to observe these substances. It is the scale between macroscopic scale and quantum scale.
