Not permanent. They can be reclaimed, but that usually doesn't happen for many years until after the end of life for the mine.
- ghouse 8y agoReclamation does not un-concentrate the materials found in the impoundment. Typically a "Mine Plan of Operations" which includes the reclamation plan is a contouring of the topography and vegetation. Some mines require indefinite groundwater treatment due to leaching from tailings ponds or other mine activity. The cost responsibility for this _indefinite_ process is sometimes borne by the state following bankruptcy of a mine.
