Here are extracts from an excellent article blog article called Ghost Town. I repeat only the few paragraphs that deal with towns that reverted to the ghosts as a result of mine closure.

Australia: Most ghost towns in Australia were usually formed after the end of mining operations or the removal of railway services. They are spread throughout the country and are located in every state and territory. Some ghost towns in Australia include Cassilis in Victoria, Farina in the far north of South Australia and Goldsworthy in Western Australia.

Ethiopia: Dallol is a former mining town in Ethiopia. It is located in the Dallol crater, were the temperatures can rise as high as 104° Fahrenheit (40° Celsius). Therefore, it was one of the hottest inhabited place on Earth when people lived there.

Mexico: Real de Catorce was once a flourishing silver mining town in northern Mexico. Its dramatic landscapes and buildings have been used by Hollywood for movies such as The Mexican (2001) with Brad Pitt and Julia Roberts.

Namibia: Outside Luderitz, Namibia there are two ghost towns, Elizabeth Bay and Kolmanskop. Both were diamond mining towns and have been partly covered by the shifting sands of the Namib Desert. There is also the ancient city of Carthage, which was rendered a ghost town by the Romans, revived by the same empire, and then destroyed again a few centuries later, with Tunis becoming the central city. Suburban settlement later occurred in the Carthage area.

United States: Old mining camps that have lost most of their population at some stage of their history, such as Central City, Colorado; Aspen, Colorado; Virginia City, Montana; Marysville, Montana; Tombstone, Arizona; Deadwood, South Dakota; Park City, Utah; Crested Butte, Colorado; or Cripple Creek, Colorado are sometimes included in the category, although they are active towns and cities today.
