how is limestone extracted mining - MC World.INC

In the pit mining technique, workers use a large metal tube to bring up a core of gem-bearing gravel. They typically extract a core from three to twenty-four meters deep. Because the rubies are extremely hard, the mother-rock is then eroded away from around them and, thus freed, they wash downstream.

How to extract the limestone from the ore

Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.
