Silica sand, with its high crush resistance and natural abundance, serves as a key proppant in hydraulic fracturing. Injected into fractures within deep rock formations, silica sand props open the fissures, allowing oil and gas to flow more freely. This essential role in fracking enhances the efficiency of hydrocarbon extraction.
