This is carried out via heap leaching and tank leaching. In heap leaching, cyanide is sprayed over crushed ore, dissolving the gold onto collection pads. This process is repeated until all the gold has been recovered. In-tank leaching, gold ore is mixed with cyanide in large tanks in a more controlled way than in heap leaching.
