Leaching agents are chemicals used to extract valuable metals (e.g., gold, copper, uranium) from ores by dissolving them into a solution. Common agents include cyanide (for gold/silver), sulfuric acid (for copper), and thiourea (alternative to cyanide). They enable cost-effective metal recovery from low-grade ores but require strict environmental controls to prevent contamination.
