The diatomite was modified by a grinding method to obtain a magnesium hydroxide -modified diatomite composite material. The prepared material was used as an adsorbent for the adsorption of anionic dye congo Red. The influence of time, pH, concentration, and other conditions on the adsorption properties of Mg(OH) 2 modified diatomite is studied ...

Methods used in the past to attempt to extract the hydrocarbons from mined diatomite ore included solvent extraction and retorting, using a Lurgi Retort. With the solvent method there are problems getting the solids to drop out of solution. In some methods an emulsion of oil, solvent and water may form.

Asphalt mixture is susceptible to moisture damage under the effect of freeze-thaw (F-T) cycles.
