Silica (Frac) Sand Mining - Minnesota Issues Resources Guides

There is interest in developing new industrial silica sand mines in Minnesota due to a rapid expansion of shale oil and gas development over the past decade and the use of the hydraulic fracturing extraction method. Silica sand mining has been a divisive topic in Southern Minnesota.

Silica sand mining Minnesota Pollution Control Agency

The potential air pollutants of most concern from frac sand mining are airborne particles, including particles less than 10 microns in size (PM 10), particles less than 2.5 microns in size (“fine particles” or PM 2.5), and crystalline silica, which ranges across both size categories.

DNR and Silica Sand Minnesota DNR

An unknown number of silica sand mines produce silica sand for construction and agricultural uses. Silica sand mines producing frac sand may or may not process the sand on-site. Off-site processing plants that receive silica sand from various mining operations in Minnesota and Wisconsin are also found in Minnesota.

Sand mining - Wikipedia

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.

What Is Silica Sand How Is It Different From Regular Sand?

Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral.

Sand Extraction: 1. Introduction

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
