Feb 08, 2019 The gold-silver ratio: The gold-to-silver ratio is a commonly cited figure that represents the amount of silver required to purchase one ounce of gold. This ratio tracks the prices of these metals relative to each other and can indicate when one is potentially cheaper or more expensive than usual.

Hard Rock Mining Gold And Silver Ore And Processing It

Hard Rock Mining Gold And Silver Ore And Processing It

The gold and silver bearing liquid, called pregnant solution, is separated from the ore by various drainage and filtration processes. The most common methods to remove the gold and silver involve activated carbon, or zinc precipitation. The carbon method requires an additional step where the metals are removed from the carbon.

Chemically, silver is an element with the symbol Ag and atomic number 47. It belongs to noble metals. Silver is in gold’s shadow, although it is also a unique metal. It is much more abundant than gold, but silver is still one of the least naturally occurring metals. In the Earth’s crust, silver occurs 800 times less frequently than copper.
