Diatomite, a soft, porous, fine-grained, lightweight, siliceous sedimentary rock, is produced by the accumulation and compaction of diatom (Class Bacillariophyceae) remains. The cell wall of living diatoms is impregnated with silica (amorphous hydrous, or opaline (SiO2.nH2O)), which preserves ornate and highly porous structures (Armbrust, 2009).

The primary binder was ordinary Portland cement (OPC) type 42.5 with an average particle diameter of 21 µm and a specific surface area of 3.85 × 10 3 cm 2 /g. Calcined diatomite with an SiO 2 content of 91.87% was also used as the supplementary cementitious material. The average diameter and specific surface area of the diatomite …

The diatomite was then processed at Invertote, and production was continued by hand excavation until the early 20th Century. A later revival of the industry, using mechanical excavation occurred in the 1950's. However, the mechanical extraction introduced impurities which generated an inferior quality ore.

Diatomite, a rock formed by the accumulation of opaline diatom frustules, is a preferred raw material for the manufacturing of filters. Its uniqueness relies on the high porosity and inertness of the frustules. The presence of carbonates in some diatomite ores hinders these properties. The purpose of this study was to identify the type of carbonates …
