High‑purity natural anhydrite — an anhydrous calcium sulfate with exceptionally high mineralogical purity — is presented as a stable raw material suitable for cement technologies, dry building mixes and specialised industrial processes. The material is sourced from natural deposits, and its consistent composition is confirmed by XRF and XRD laboratory analyses. The anhydrite phase content reaches around 99%, making it one of the highest‑quality options available in the mineral raw materials segment.
