St. Peter Sandstone abandoned mining location in Pacific, Missouri. Mining. The St. Peter Sandstone was first mined in Missouri in the 1870s for glass sand. Early mining was conducted at the surface and underground, and was concentrated near the town of Pacific. Presently (2012) there are four companies producing St. Peter in Missouri.

Devonian rocks supply a variety of mineral resources. A Devonian sandstone formation known as the Sylvania Sandstone located at or near the surface in Wayne and Monroe counties contains high silica, uncontaminated sand grains. Mining sandstone involves different techniques (i.e., blasting, crushing, etc.) and the process is more expensive.

Our surface mines near the Mauricetown facility use natural gas, fuel oil and electricity, to produce whole grain silica through dredge mining. The reserves are mined from alluvial sands in the Maurice River Valley and are similar to those found in the Cohansey, Bridgeton and Cape May deposits. The silica sand deposits are 99% pure silica, with ...

When the Edinburgh Geological Survey analysed a sample of sandstone from Lochaline in 1923 they found one of the purest deposits of silica sand in the world. Despite this it was not mined immediately- imported silica sand was quite cheap and the venture was not considered economic. When World War Two broke out, however, these imports were cut off.
