MINING SILVER How Is Silver Mined?

The main method of silver extraction is the cyanide process, aka cyanidation 1. The ore is crushed into pieces to expose the silver. 2. About 1.4-2.3kg of lime (calcium hydroxide, Ca(OH)2) is added to every ton (1000kg) of silver ore to create an acidic environment. 3. Cement is added into the mixture, as well as water or a cyanide (CA-) solution.
