  • open pit/underground mining

    underground method is commonly used to mine a higher grade ore as compared to open pit method: higher costs of mining deep under ground are only set off by a high grade of ores. technically, there is no limit on depth of ore occurrence for the underground mining method, but today the deepest uranium mines are no more than 2 km deep.
