Open-pit mining - Wikipedia
Open-pit mines are typically worked until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. [citation needed] After open-pit mines are closed, they are sometimes converted to landfills for disposal of solid waste.Some form of water control is usually required to keep the mine pit from becoming a lake.
