Extraction. 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.
