🧠 The Chemical Replacement
MacArthur-Forrest Cyanide is a two-step process to "trick" Silver and Gold out of their ores and into a pure metallic bar.

🗺️ The Extraction Route
1. Step 1: Leaching: Silver is dissolved in Sodium Cyanide () in the presence of air (). It forms a soluble complex.
   
2. Step 2: Recovery: The Silver is currently "hiding" in the solution as an ion. To get it back, we need a "bully" metal that is more reactive.
3. The Role of Zinc: Zinc () is higher in the reactivity s
