The diagram depicts a cross section of three different kinds of mines, along with structural elements of the underground shaft and slope mines. The shaft mine has compartments for a skip hoist, elevators called cages, and service facilities such as ventilation ducts.

CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process. In the latter case leaching takes place in tanks dedicated for leaching followed by adsorption onto carbon in tanks dedicated for adsorption. Gold Leaching. Leaching can be assimilated to the principle of preparation of tea.
Gold is a precious metal and also a chemical element with atomic number 79. When not mixed with other metals it is reddish yellow, heavy, soft, easy to work with, and conducts electricity readily. Gold is part of a group of metals called noble metals, which include gold, silver, and platinum; they all resist chemical action, do not corrode, and are not easily changed by acids.

In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Therefore whenever gold is found encased in pyrite, it is always present as free gold and not as some type of gold sulphide.
