Cyanidation is a chemical process used to extract gold and other precious metals from ore. In this method, a cyanide solution is applied to the crushed ore, allowing the metal to dissolve into the solution. This process is effective because cyanide can selectively bind to gold, making it easier to separate from other materials. After the gold is dissolved, the solution is processed to recover the metal, often through methods like carbon adsorption or electrolysis. While cyanidation is efficient, it raises environmental concerns due to the toxicity of cyanide, necessitating careful management and regulation in mining operations.
