Mining operations commonly employ this process to recover gold from low-grade or refractory ore. CIL Principle. Leaching: The gold ore is crushed and ground to a fine powder. It is then mixed with a cyanide solution, usually sodium cyanide, to create a slurry. The cyanide solution reacts with gold in the ore, forming soluble gold-cyanide complexes.
