Silver mining Wikipedia

Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 o C (1764 o F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes.

How is Silver Mined APMEX®

Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.

Gold cyanidation Wikipedia

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au(s) + 8 NaCN(aq) + O 2 (g) + 2H 2 O(l)→ 4 Na[Au(CN) 2](aq) + 4 NaOH(aq). In this redox process, oxygen removes, via a two-step reaction, one electron from each gold atom to form the complex Au(CN) − 2 ion.. Application. The ore is comminuted using grinding machinery. .

The reaction normally occurs within 5 to 10 minutes. In the secondary reaction, the cyanate is further oxidized under near-neutral conditions and converted to harmless carbon dioxide and nitrogen gases. In the second reaction tank, the pH of the waste is measured, and acid is injected to lower pH to 7-8. This process takes 2 to 5 minutes.
