>20 Pros and Cons of Open Pit Mining
Pros And Cons Of Open Pit Mining. Are you aware that open pit mining is responsible for extracting around 90% of the world's mineral ores? This type of mining involves digging a large hole in the ground to access valuable minerals and metals. Open pit mining has been used for centuries, but it comes with both advantages and disadvantages.
