Mining in Minnesota

Silica sand is a very fine sand composed of quartz (a white to colorless mineral) and is mined in the southeastern part of Minnesota. It is used to make glass, as a source of silicon, and is used in oil drilling to improve the flow of oil to oil wells. Granite and limestone are used in the construction of homes, buildings, roads and tombstones.

What is Silica Sand?

Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.
