open open cast mining advantages
Open
Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Differences between underground mining and open pit mining
When the minerals are found in rich veins but in large volumes of sterile rocks, the only way to mine them is the underground mining method. These consist of opening galleries, tunnels, and other forms of mining art that allow us to take advantage in an orderly manner of the veins in their three-dimensional development.

Lesson 7.3: Mechanical Surface Mining Methods
Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut. Therefore, reclamation occurs

Large, low-grade ore deposits are usually economically attractive because it permits high recovery of the resource and allows sufficient space for large and efficient mining equipment. An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery.
