Silica sand: Overview
Why most industrial sand ends up down oil wells
What this tab covers What the commodity is used for, why, in what volumes and with what alternatives, and its chain from mine or field to end user. Also the latest price moves, top recent news, three things to know, and buttons into each tab.Key uses
| Use | Share | Annual volume | Why this commodity | Alternatives |
|---|---|---|---|---|
| Hydraulic fracturing proppant (frac sand) and well packing and cementing sand | 81% | about 97 million t a year in the USbasis | Frac sand props open the cracks made in shale so oil and gas can flow. Round, hard, high-silica grains of a tight size range resist crushing at depth, and sand costs far less than ceramic proppant. Shale drilling in Texas and Oklahoma made this the largest single use of industrial sand in the world's largest market. USGS MCS 2026, Sand and Gravel (Industrial) | Sintered bauxite and kaolin-based ceramic proppants (deeper, higher-pressure wells) Petroleum coke-based lightweight proppant (growing in 2025) Resin-coated sand |
| Glassmaking: containers, flat glass, fibreglass and specialty glass | 7% | about 8.4 million t a year in the USbasis | Silica is the main ingredient of soda-lime glass, typically the largest part of the batch. Clear glass needs sand above 95% silica with very little iron, which is why low-iron 'silver sands' such as Fontainebleau or Lochaline travel long distances. Outside the US, where frac sand is small, glass is usually the leading use. USGS MCS 2026; Conway, Material World (2023) | Recycled cullet (about 33% of US glass containers are recycled) No mineral substitute for silica as the glass former |
| Fillers, foundry moulds and cores, water filtration and recreational sand | 7% | about 8.4 million t a year in the USbasis | Foundries use silica sand because it withstands molten metal, is cheap and can be reclaimed. Water works use graded sand beds as a cheap, inert filter. Ground silica is a hard, white filler in paints, plastics, sealants and grouts. Sports and recreational sand needs consistent grain size and drainage. USGS MCS 2026 | Chromite, olivine, staurolite and zircon sands (foundry) Garnet, ilmenite and anthracite (filtration media) Calcium carbonate, kaolin and talc (fillers) |
| Chemicals, abrasives, silicon and ferrosilicon, ceramics, traction and metallurgical sand | 1% | about 1.2 million t a year in the USbasis | High-silica sand and quartz feed sodium silicate and silicon carbide plants and, as lump quartz, silicon metal and ferrosilicon furnaces. Trains drop sand on rails for grip when braking. These are small tonnages but often need tight chemistry. USGS MCS 2026; Conway, Material World (2023) | Garnet, olivine and slags (abrasive blasting) Quartzite lump instead of sand for silicon furnaces |
| High-purity quartz for fused-quartz crucibles (solar and semiconductor wafers), fibre optics and lamp tubing | n/a | about 100,000 t a year from the USbasis | Crucibles that hold molten silicon while single crystals are pulled must be made of quartz with under 100 ppm of impurities. Spruce Pine, North Carolina, supplies quartz above 99.999% purity; China announced 35 million t of HPQ reserves in 2025 but at 99.995-99.998%. Prices run from $500 to $12,000 per t (2025). USGS MCS 2026, Quartz (High-Purity and Industrial Cultured Crystal); Conway, Material World (2023) | Cultured (synthetic) quartz, rarely used because it costs more No economic substitute for most HPQ uses (USGS) |
From mine to user
- 1. Deposit selection Quartz-rich sands and sandstones occur widely; value depends on silica content, iron, grain shape and size. Clear glass needs over 95% SiO2 and low iron.
- 2. Quarrying or dredging Mostly open pits with loaders or dredges. The US had 207 operations run by 131 companies in 38 states in 2025 (USGS).
- 3. Washing and attrition scrubbing Water washing removes clay; scrubbing strips iron-stained coatings from grains.
- 4. Classification and beneficiation Screens and hydrocyclones size the sand; magnetic separation, flotation or acid leaching remove iron and heavy minerals for glass and HPQ grades.
- 5. Drying or wet sale Rotary or fluid-bed dryers for most grades; in the Permian, undried 'wet sand' is increasingly sold straight to wells to cut cost and dust (USGS 2025).
- 6. Logistics Sand is cheap and heavy, so freight decides markets. Shipping Wisconsin sand to Texas added $50-60/t in fees (Rystad via WPR, 2020); Atlas Energy's Dune Express conveyor moved 5.9 Mt in 2025.
- 7. End users Well-site pressure pumpers, glass furnaces, foundries, water works and chemical plants. US average value was about $36/t in 2025 (USGS).
