The process described in the question is known as cyanide leaching, and it is commonly used to extract silver from its ore. Let's break down the steps involved in this process:
1. Grinding the ore: The ore containing silver is first crushed and ground into fine particles. This increases the surface area of the ore, allowing for better contact between the ore particles and the leaching solution.
2. Leaching with dilute potassium cyanide solution: The ground ore is then mixed with a dilute solution of potassium cyanide. Potassium cyanide (KCN) is a highly toxic compound that forms a complex with silver called potassium argento cyanide (KAg(CN)2).
3. Formation of potassium argento cyanide: In the presence of potassium cyanide, the silver in the ore reacts to form potassium argento cyanide, which is soluble in water. This reaction can be represented by the following equation:
Ag + 2KCN + H2O → KAg(CN)2 + KOH
4. Separation of silver: The resulting solution containing potassium argento cyanide is then separated from the remaining solid ore particles. This can be done by filtration or other separation techniques.
5. Recovery of silver from the solution: To recover silver from the potassium argento cyanide solution, various methods can be employed. One common method involves the addition of metallic zinc to the solution. The zinc reacts with the potassium argento cyanide, displacing the silver and forming solid silver particles. These particles can then be collected and further processed to obtain pure silver.
Therefore, based on the given information, the element being extracted from its ore using cyanide leaching is silver (Ag).
