The more gold which has to be leached, the more cyanide required. In practice, a balance is sought so that there is sufficient cyanide to leach the gold, but not so much that excess cyanide is left at the end of the adsorption process to be lost to tailings.

In Situ Leach (ISL) Mining of Uranium Robert B. Laughlin

In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the ore where it is in the ground, and recovering the minerals from it by dissolving them and pumping the pregnant solution to the surface where the minerals can be recovered.

What is "In Situ" Mining? Protect Water for Future

The mining solution is injected into the aquifer under pressure in order to leach the uranium out of the ground. The leach solution strips the uranium out of the aquifer. Along with radioactive uranium, arsenic, selenium, radium and lead are also extracted. In situ leach uranium mining must be done directly in a water-bearing aquifer.
