Diatomite is a chalk-like, soft, friable, earthy, very fine-grained, siliceous sedimentary rock, usually light in color (white if pure, commonly buff to gray in situ, and rarely black). It is very finely porous, very low in density (floating on water at least until saturated), and essentially chemically inert in most liquids and gases.

Diatomite formation seems to have been particularly prevalent in the Miocene, the Plio-Pleistocene, and during the early to middle Holocene periods. Because of the properties conferred on diatomite sediment by a high silica content and a fine-grained texture, these extensive natural deposits are often exploited commercially.

april 2005 hos This work determined the influence of humic acid (HA) and fulvic acid (FA) on the interaction mechanism and microstructure of Ni(II) onto diatomite by using batch experiments, X-ray photoelectron spectroscopy (XPS), and extended X-ray absorption fine structure (EXAFS) methods.

African Diatomite Industries Limited (ADIL) is the leading processor & supplier of fresh water Diatomaceous Diatomite can absorb liquid three times the weight of its own. The market for diatomite was driven by vanity of end-user industries such as water treatment, crop protection chemicals and absorbent among others. Huge demand for diatomite from filtration mediums has been the major factor for the growth of diatomite in past few years.

These properties make it useful as a filter media, an absorbent, and as a lightweight filler for rubber, paint, and plastics. Diatomites are formed in both marine and freshwater systems where the processes of diatom formation, diatom preservation, and sedimentation conspire to produce diatomaceous sediments. Diatomite formation seems to have been particularly prevalent in the Miocene, the Plio-Pleistocene, and during the early to middle Holocene periods. The term diatomite is applied both geologically and commercially to the nearly pure sedimentary accumulation of diatom frustules—the microscopic skeletons of unicellular aquatic algae belonging to the class of golden brown algae, Bacillariophyceae.

Diatomite is a near pure sedimentary deposit consisting almost entirely of silica. Diatomite is a soft, friable and very fine-grained siliceous sedimentary rock composed of the remains of fossilized diatoms. Chalky to the touch and often light in color, diatomite can be white if pure, but more commonly it is buff to gray in situ, or sometimes black. Diatomaceous earth or diatomite is a light-colored sedimentary rock composed chiefly of siliceous shells (frustules) of diatoms.
