Silicon and oxygen are the earth's two most abundant elements and together they make silica, one of the earth's three most common rock forming minerals. Silica occurs in three main crystalline forms. The principal occurrence is as the mineral quartz but it also occurs in other rarer mineral forms known as tridymite and cristobalite.

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.
It recently completed bulk metallurgical test work that confirmed that the project can produce a high quality silica sand product with 99.8% silica content and low levels of contaminants. The company is also waiting on the grant of its mining lease application and plans to drill 82 holes in July/August to further grow its resources.

Silica is the second most abundant mineral on Earth, with the planet made up of nearly 30-percent. Silica's most common form is as a sand, however it can be processed into silicon which leads to many uses in today's life. Silica is a primary ingredient in solar panels and can also be found in the circuit boards that power all electronics.
The dissolution of silica in water can be described as follows: where s and aq represent solid and aqueous phases. The solubility of silica minerals decreases as a function of increasing packing density of the silica tetrahedra and long-range crystal order. Solubility of quartz at ambient temperatures and neutral pH is commonly 3–7 mg Si L ...
Most of the known commercial silica (SiO2) deposits in Victoria are mineral sands and gravels of Tertiary and Quaternary age.

Silica sand — particularly the grains mined in North America — is typically found inland, deep under the earth's surface, left behind by ancient glacier movements. In almost all cases, silica sand is mined using an open-pit or dredging method, effectively digging large holes to remove sand or scooping it from lake and river beds.
